Exploiting the Diaper Bundle Dashboard: The Advanced Step-by-Step Guide to Mixing Sizes for Two Under Two
How to mix diaper sizes within one Hello Bello or Honest Company subscription bundle for two children.
A full cost-per-diaper, materials, and shipping comparison between Hello Bello and Dyper subscriptions.
By James T. Reilly · September 25, 2026
Part of the complete guide to diaper delivery subscriptions for multi-child and small-age-gap households.
Bottom line up front: Hello Bello is the cheaper, higher-volume, wipes-included option, and it wins on pure cost-per-diaper at every size once you account for the fact that its $79.99 bundle already includes 4 packs of wipes at no extra charge. Dyper costs more once you add a comparable wipes supply, but you're buying a materially different product — a fully unprinted, unscented, 100% bamboo-viscose diaper with OEKO-TEX Standard 100 certification and a legitimate commercial-composting pathway, versus Hello Bello's printed, plant-derived-core diaper that isn't marketed as compostable. For a high-volume, multi-child household, the decision usually comes down to whether the composting and bamboo-viscose story is worth roughly $20–35 more per month than Hello Bello's all-in bundle price — and this audit gives you the actual numbers to make that call rather than a marketing summary of either brand.
Both brands publish enough pack-count and pricing data to build a real per-diaper cost table — the catch is that the two subscriptions aren't structured the same way. Hello Bello's $79.99 bundle price already includes both diapers and wipes. Dyper's $80 box price covers diapers only; wipes are a separate purchase. Any comparison that ignores this structural difference will make Dyper look artificially competitive, so this table breaks out both the diapers-only cost and the realistic all-in cost with a comparable wipes supply.
| Size | Weight Range | Diapers Per Bundle | Bundle Price (incl. 4 wipes packs) | Cost Per Diaper (bundle-blended) |
|---|---|---|---|---|
| N | Up to 10 lbs | 238 | $79.99 | ~$0.34 |
| 1 | 8–12 lbs | 238 | $79.99 | ~$0.34 |
| 2 | 10–16 lbs | 217 | $79.99 | ~$0.37 |
| 3 | 14–24 lbs | 182 | $79.99 | ~$0.44 |
| 4 | 22–37 lbs | 154 | $79.99 | ~$0.52 |
| 5 | 27+ lbs | 133 | $79.99 | ~$0.60 |
| 6 | 35+ lbs | 119 | $79.99 | ~$0.67 |
The "cost per diaper" column above is the bundle price divided by diaper count, meaning it technically includes the value of the 4 free wipes packs — it understates the true diaper-only cost slightly, but since Hello Bello doesn't sell the wipes and diapers separately at different prices within the bundle, this blended figure is the most honest number available rather than an estimate we're constructing ourselves.
| Size | Weight Range | Diapers Per Box | Box Price (regular) | Box Price (wide, sizes 3–4 only) | Cost Per Diaper |
|---|---|---|---|---|---|
| 1 | Under 10 lbs | 264 | $80 | — | ~$0.30 |
| 2 | 6–16 lbs | 224 | $80 | — | ~$0.36 |
| 3 | 13–22 lbs | 184 | $80 | $88 | ~$0.43 (regular) / ~$0.48 (wide) |
| 4 | 20–31 lbs | 140 | $80 | $88 | ~$0.57 (regular) / ~$0.63 (wide) |
| 5 | Over 28 lbs | 120 | $80 | — | ~$0.67 |
Dyper's box price is flat at $80 regardless of size — you get fewer diapers as the size increases, the same structure Hello Bello uses, but Dyper's flat pricing means the cost-per-diaper climbs faster at the higher sizes since the box price never adjusts downward to compensate. Briefs (training pants, sizes 2T–6T) always ship 100 pieces per box regardless of size, at the same base pricing structure, according to Dyper's published size chart.
Dyper sells bamboo viscose wipes separately, and pricing varies significantly by purchase format — a single 60-count pack has listed around $8.99 at some retailers, while a bulk 1080-count case (equivalent to 18 packs of 60) has been priced around $79–80, which works out to roughly $4.40–4.45 per 60-count pack when bought at that bulk volume. To match Hello Bello's included 4 packs (240 wipes) as an add-on purchase, a Dyper household is looking at somewhere between roughly $18 (buying in bulk and prorating) and $36 (buying four individual 60-count packs) in additional monthly cost, depending entirely on purchase format.
| Scenario | Hello Bello (all-in) | Dyper (diapers) | Dyper (+ 240 wipes, individual packs) | Dyper (+ 240 wipes, bulk-prorated) |
|---|---|---|---|---|
| Size 2 / comparable infant size | $79.99 | $80.00 | ~$115.96 | ~$97.78 |
| Size 4 / comparable toddler size | $79.99 | $80.00 (regular) | ~$115.96 | ~$97.78 |
The real-world verdict: at every size we can verify, Hello Bello's all-in bundle price is lower than Dyper's diapers-plus-wipes cost — by roughly $18 to $36 a month depending on how you buy Dyper's wipes. For a high-volume, multi-child household running this cost difference across 12+ months, that's a meaningful gap, not a rounding error. Dyper is not the budget play in this matchup; it's the premium-materials play, and the rest of this audit is about whether that premium is justified for your household.
Hello Bello's diapers are built around a totally chlorine-free (TCF) fluff pulp sourced from sustainably managed forests, combined with a high-performance super absorbent polymer (SAP) core, polypropylene/polyethylene/polyester nonwoven fibers for the structural layers, a plant-derived PLA (polylactic acid) nonwoven fiber, spandex strands for the leg and waist elastics, and an elastomeric film. The brand states the diapers are made without chlorine processing, artificial fragrance, phthalates, parabens, lotions, latex, or the organotin compounds TBT/DBT/MBT.
Functionally, this is a conventional-architecture diaper — fluff pulp plus SAP is the same absorbency backbone used by most mainstream disposable brands — with the plant-derived PLA nonwoven and TCF pulp sourcing as the sustainability differentiators, rather than a structurally novel diaper. The printed designs are a core part of the product identity (25+ rotating prints), which means the outer cover is a standard printed nonwoven rather than an unprinted natural-fiber layer. Hello Bello's fragrance-free product line specifically carries National Eczema Association approval, which is a relevant signal for households managing a child with documented sensitive skin, though it applies to the fragrance-free variant specifically rather than the full printed lineup.
Dyper's defining material claim is a diaper built with over 55% plant-based materials, with 100% natural fibers specifically at the layer touching the baby's skin — the topsheet is viscose fiber derived from bamboo, a fast-growing, low-input crop that the brand and third-party bamboo-industry sources describe as requiring no irrigation, pesticides, or fertilizer to cultivate, harvestable in 3–5 years compared to 30+ years for hardwood pulp sources. The diapers are unprinted, unscented, soft-touch, and are certified to the Standard 100 by OEKO-TEX benchmark — a widely recognized Swiss textile-safety certification that tests for a defined list of harmful substances, which is a genuine third-party verification credential rather than a brand's own claim about itself.
Dyper's marketing describes the product as free of pigments, dyes, rubber, latex, chlorine, alcohol, lotions, TBT, and phthalates. What isn't fully detailed in the publicly available product description is the specific composition of the absorbent core beneath the bamboo-viscose topsheet — the "55% plant-based" figure implies the core still relies on some proportion of standard absorbent materials (very likely a fluff-pulp-and-SAP structure similar in function to Hello Bello's, since bamboo viscose alone isn't typically used as a diaper's primary liquid-locking mechanism in the way SAP is). We're flagging this rather than guessing at the exact ratio, because Dyper's own materials disclosure focuses on the skin-contact layer and the compostability story, not a full itemized bill of materials for the core — a genuinely more transparent brand from a pure documentation standpoint would publish that breakdown the way a small number of premium competitors do, and Dyper, based on what's publicly available, doesn't appear to.
Update, added after The independent PFAS lab testing review: independent EPA-certified lab testing conducted after this article's original research found Dyper's diaper tested completely clean for indications of PFAS — a genuine, positive confirmation of the OEKO-TEX certification discussed above, in contrast to a same-certification competitor (Kudos) that did not test clean in the same study. Full details, including the specific testing methodology and why the result diverged from a same-certified competitor, are in the independent PFAS lab testing review.
This is the section where a lot of diaper-subscription content quietly starts inventing numbers, so it's worth being direct: neither brand publishes independent, third-party lab-tested liquid-capacity or absorption-speed figures that we could locate, and we're not going to assign either product a specific milliliter capacity or absorption-rate claim we can't source. What we can report:
For newborn liquid blowouts specifically: the more relevant design features are poo-pocket construction, leg-cuff design, and waistband stretch, not topsheet material — and neither company's public documentation gives a detailed comparative breakdown of these structural features against each other. Parent-reported experience (rather than lab data) suggests fit consistency and correct sizing matter more for blowout prevention than the topsheet fiber source, which tracks with general disposable-diaper engineering knowledge — a diaper that fits snugly at the leg and waist will outperform a looser diaper made of "better" material every time.
For heavy overnight toddler wetting: this is the scenario most likely to expose a real difference between the two products, precisely because of the reported faster-wet-feeling and fray risk noted for Dyper's bamboo viscose topsheet under heavy saturation. A toddler who is a genuinely heavy overnight wetter is the profile most likely to test the limits of Dyper's standard (non-overnight-specific) product line, though we did not find a dedicated "overnight" SKU variant clearly documented for Dyper the way some competitors offer. Households in this situation should treat this as a real open question to test directly with a trial pack rather than something either brand's marketing will resolve for you.
Where Dyper has an unambiguous, well-documented structural advantage is end-of-life disposal. The entire diaper is described as compostable, and the company operates REDYPER, a program allowing subscribers to bag and ship used diapers back to Dyper (or its composting partner, TerraCycle, per some program descriptions) for centralized commercial composting rather than landfill disposal. Reporting on this program's cost has varied across sources and years — some older coverage described a separate monthly REDYPER fee (reported around $50/month in older material), while a more recently updated review describes the service as included at no additional charge. Given that conflict, we'd rather flag it plainly than assert either figure as current: confirm REDYPER's current cost structure directly with Dyper before assuming it's free or budgeting for a $50/month add-on, since our sources genuinely disagree and we don't want to guess on a detail that materially affects your monthly cost.
Hello Bello does not market a composting or take-back program for used diapers; standard disposal is landfill, as with most mainstream disposable diaper brands. For a household where end-of-life environmental impact is a primary decision driver — not just the raw material sourcing, but what happens to the product after use — this is the single clearest differentiator in Dyper's favor, and it's backed by an actual operating program rather than aspirational marketing language.
Hello Bello processes orders within 1–2 business days (orders placed after 1 p.m. PDT may roll to the next business day), with delivery typically arriving 3–7 business days after processing for the continental US — longer for Hawaii, Alaska (up to 21 days), and APO/FPO addresses (1–8 weeks depending on base location).
Dyper's published delivery structure describes orders shipping within two to three days of placement, with typical first-box arrival in under a week domestically. Beyond the standard cycle, Dyper offers an SOS reordering option intended for households that are about to run out before their next scheduled shipment — the specific turnaround window for SOS orders has been described in older company materials as a matter of hours rather than days, though we'd treat any specific hour count from older press material as potentially stale and recommend confirming current SOS turnaround directly rather than planning around a multi-year-old figure.
This is a genuine point of difference. Dyper's delivery frequency is adjustable across a wide range — from every 2 weeks up to every 12 weeks — giving households significant control over how much inventory arrives per shipment without changing the box's contents. Hello Bello's frequency adjustment is also available through account settings, but the brand's own materials don't advertise a specific range as wide as Dyper's 2-to-12-week spread; Hello Bello's system is generally described around the standard monthly cycle with the ability to adjust the date, rather than marketed as a wide-range frequency dial the way Dyper's is.
For a multi-diapering household trying to solve the volume-matching problem covered in the portal-optimization piece of this series, Dyper's wider frequency range is a genuine practical advantage if you're trying to compress delivery cycles to keep pace with a high-consumption newborn without over-ordering on a slower-consuming older sibling's size.
Hello Bello charges $5.95 for orders under $35 and $1.95 for orders of $35 or more, based on published account documentation, with a $25 surcharge for Hawaii and Alaska deliveries. Dyper advertises free shipping on its standard box, with applicable sales tax added based on delivery location — meaning Dyper's headline box price is closer to the true out-of-pocket cost than Hello Bello's, which typically adds a small shipping charge on top of the bundle price.
This is an area where neither brand publishes a clearly detailed, specific policy for unopened-pack returns or exchanges when a child rapidly outgrows a size — a real and common scenario in fast-growing infants, and one this guide would be doing readers a disservice to guess at. General subscription-commerce norms (and Hello Bello's own emphasis on being able to freely adjust size, frequency, and contents from the account dashboard before the next order ships) suggest the more reliable strategy for both brands is proactive resizing before your next shipment processes, rather than relying on a post-purchase return for a pack that's already shipped in the wrong size. If a formal return/exchange policy for unopened packs exists at either company, it wasn't clearly documented in the sources available for this guide — check each brand's current customer service policy directly before assuming either will accept an unopened pack back.
A single month's price difference is easy to dismiss as noise. Annualized across a full year — which is the realistic horizon for a household with an infant, since most babies pass through 4–6 diaper sizes in their first 18 months — the gap becomes harder to ignore.
| Scenario | Monthly Cost | 12-Month Cost | 12-Month Cost, Two Children (separate boxes/bundles) |
|---|---|---|---|
| Hello Bello, single size, all-in | $79.99 | $959.88 | $1,919.76 (two separate bundles) |
| Dyper, single size, diapers only | $80.00 | $960.00 | $1,920.00 |
| Dyper, single size, + wipes (individual packs) | ~$115.96 | ~$1,391.52 | ~$2,783.04 |
| Dyper, single size, + wipes (bulk-prorated) | ~$97.78 | ~$1,173.36 | ~$2,346.72 |
A few things worth naming directly in this table rather than leaving implicit:
Neither price nor materials tells the whole story of whether a subscription brand is a safe long-term bet for a household that may be ordering from it monthly for 2+ years across multiple children. A brief accounting of what's publicly verifiable about each company's track record:
Hello Bello was co-founded by actors Kristen Bell and Dax Shepard and launched in 2019, positioned explicitly around making "premium" baby products available at prices closer to mainstream than to the premium-organic tier. The brand states it has donated millions of diapers to non-profits since launch, including a program donating a year's worth of diapers to a family each week throughout 2020 and 2021, and operates a Diaper Registry Fund allowing crowdsourced diaper funding from friends and family. It has received recognition from several parenting and consumer publications, including being named Best Diaper Subscription by outlets covering the category in multiple recent years. The brand is also sold through major mass retailers (Walmart, Target-adjacent drugstore chains, Kohl's, Albertsons), which is a meaningful signal of retail-scale manufacturing and distribution infrastructure behind the subscription arm specifically — a brand selling at Walmart scale has different supply-chain resilience than one that exists purely as a direct-to-consumer subscription operation.
Dyper was founded in 2014 under parent company STYR Labs, an app-and-subscription technology company, and grew rapidly in its early years (self-reported growth north of 500% per month shortly after its 2019 product-line expansion into wipes and diaper cream). Dyper's sustainability positioning is backed by concrete, checkable program details rather than only marketing language: OEKO-TEX Standard 100 certification is a real third-party textile-safety credential, and the brand's purchase of carbon offsets through Cool Effect, directed toward the Alto Mayo Reforestation Project, is a named, specific environmental program rather than a vague "we care about the planet" claim. Dyper is a smaller, more narrowly positioned operation than Hello Bello — it doesn't have equivalent mass-retail shelf presence in the sources reviewed here, which means its supply chain and customer-service scale are less independently verifiable through retail-partner channels, though this doesn't by itself indicate any instability, just less publicly observable infrastructure than a Walmart-stocked competitor.
Beyond the raw materials difference covered above, the two brands take opposite approaches to how much visual/product customization you get per box, which matters for households ordering monthly for years at a stretch.
Hello Bello leans heavily into design as a product feature: up to 7 selectable prints per bundle, drawn from a rotating catalog the brand describes as having launched 29 new designs in a single recent year, with shipping boxes designed to be upcycled into play structures (rocket ships, boats, and similar themed builds have been featured). For a household with an opinionated toddler, this is a real, if minor, quality-of-life factor — kids who take an interest in "their" diaper prints are, anecdotally, sometimes easier to get through a change.
Dyper takes the opposite position by design: diapers are intentionally unprinted and unscented, which is presented as part of the minimal-ingredient, minimal-processing philosophy behind the bamboo-viscose positioning — printing inks and dyes are simply not part of the product at all, rather than being formulated to be "safe" inks. This isn't a customization gap so much as a deliberate trade-off: Dyper's customization axis is delivery frequency and box format (regular, wide, briefs), not visual variety, while Hello Bello's is closer to the reverse. Neither approach is objectively better; they reflect genuinely different product philosophies, and which one fits your household is a matter of what you're actually optimizing for — engagement and cuteness, or minimal processing and an unprinted product.
For a multi-diapering household, committing to a brand and then discovering a fit or absorbency problem three weeks in is a materially bigger disruption than it would be for a single-child household — you're not just re-shopping one size, you're potentially re-shopping your entire monthly diaper logistics for multiple children at once. This makes trial-friendliness a genuinely practical factor, not just a nice-to-have.
Historically, both brands have offered some form of discounted or free first-order trial mechanism — Hello Bello has run free-gift and percentage-off first-bundle promotions (25% off in some past campaigns, per subscriber-review coverage), and Dyper has been referenced in review coverage as offering a free trial period in at least some enrollment paths. Neither brand's current, standing trial offer terms were independently confirmed in the sources used for this guide, and promotional terms in this category change frequently enough (new-customer percentage discounts, free gift thresholds, referral credits) that any specific figure cited here risks being stale by the time you read it. The actionable takeaway: check the live signup page for both brands' current new-subscriber offer before committing, and treat any trial discount as a bonus on top of the cost comparison in this guide, not a reason to skip doing that comparison.
On switching mid-subscription: both brands' account-management structure (covered in more detail in the Diaper Bundle Dashboard guide) allows adjusting size, frequency, and contents without cancelling outright, which lowers the switching cost within a brand. Switching between Hello Bello and Dyper entirely — abandoning one subscription and starting the other — carries no penalty beyond whatever's left unused in your most recent box, based on available cancellation-policy information, though Honest Company-style phone-required cancellation friction (discussed in the Diaper Bundle Dashboard guide) doesn't appear to be a factor for either brand covered here; both are described as manageable through self-service account settings.
A dimension of the sustainability comparison that's easy to overlook because it's not the diaper itself: what the box and packaging are made of. Hello Bello states its shipping boxes are fully recyclable, and actively markets the box-upcycling angle (turning the shipping box itself into a play structure) as part of the unboxing experience — a form of reuse that extends the packaging's life before it enters the waste stream at all. Dyper's packaging for the REDYPER return program specifically uses biodegradable bags and specialized shipping supplies designed to go into the same composting stream as the diapers themselves, which is a more integrated packaging-to-disposal design than a standard recyclable cardboard box, though it's also a design that only pays off if a subscriber actually participates in REDYPER rather than disposing of used diapers in standard trash.
Neither company's standard outer shipping box (as opposed to the REDYPER-specific return packaging) was described in available sources as anything other than conventional recyclable cardboard, so this isn't a meaningful point of differentiation on the outbound side — the difference shows up specifically in what happens to the box on the return leg of Dyper's composting program, which Hello Bello has no equivalent to since it doesn't operate a take-back program at all.
Is Hello Bello or Dyper cheaper overall? Hello Bello is cheaper once wipes are factored in. Its $79.99 bundle includes both diapers and 4 packs of wipes; Dyper's $80 box is diapers-only, and adding a comparable wipes supply brings Dyper's real monthly cost to roughly $98–116 depending on how the wipes are purchased.
Does Dyper's diaper contain more or less plastic than Hello Bello's? Dyper markets its topsheet — the layer touching the baby's skin — as 100% natural bamboo-viscose fiber, with the overall diaper described as over 55% plant-based. Hello Bello uses a combination of plant-derived PLA nonwoven fiber alongside conventional polypropylene/polyethylene/polyester nonwovens. Neither company publishes a full percentage-by-weight materials breakdown of the entire diaper (including the absorbent core) that would let us state a precise plastic-content comparison beyond what each brand discloses about its topsheet and stated composition.
Can I get an SOS emergency delivery if I run out of diapers between scheduled boxes? Dyper explicitly offers an SOS reorder feature for this scenario. Hello Bello doesn't appear to market an equivalent named service, though standard a-la-carte ordering outside the bundle cycle is available through the account.
Are Dyper diapers actually compostable at home, or do I need their return program? Dyper markets the diapers as compostable, with REDYPER as the take-back program for centralized commercial composting if home composting isn't practical for your household. Confirm current REDYPER program costs directly with Dyper, since published sources disagree on whether it's currently free or carries a separate monthly fee.
Which brand includes wipes in the subscription price? Hello Bello includes 4 packs of wipes (240 wipes) in every diaper bundle at no separate charge. Dyper sells wipes as a standalone product outside the diaper box price.
Does either brand offer overnight-specific diapers? We did not find a clearly documented dedicated overnight SKU for Dyper in available sources. Hello Bello's core lineup is the standard daytime/general-use design; if overnight-specific engineering is a priority, that's worth confirming directly with either brand rather than assuming the standard product is optimized for it.
Is Dyper's bamboo-viscose material safer than Hello Bello's plant-derived core? "Safer" depends on what you're measuring. Dyper carries OEKO-TEX Standard 100 certification, a recognized third-party textile-safety standard. Hello Bello's fragrance-free line carries National Eczema Association approval. Both brands state their products are made without chlorine processing, phthalates, parabens, and several other common irritants. Neither has an independent lab-tested absorbency or safety comparison against the other that we could locate.
Can I mix Hello Bello and Dyper diapers in the same household for two different children? Nothing prevents running two separate non-competing subscriptions if your household wants each child on a different brand — but doing so means paying two separate subscription base costs (and, for Hello Bello, potentially two separate shipping charges) rather than benefiting from either brand's multi-size bundle structure, which is generally the more cost-efficient path if a single brand's sizing covers both children adequately.
How does Dyper's pricing scale for a household with two children in different sizes? Since Dyper's box price is flat at $80 regardless of size, running two separate boxes for two children (one per size) means paying $160/month before wipes, rather than a discounted combined rate — Dyper's published subscription structure doesn't describe a multi-child bundle discount the way the Diaper Bundle Dashboard guide found for Hello Bello and Honest Company's two-size bundle options.
What happens to Dyper's price if I choose wide diapers instead of regular? Wide diapers, available only in sizes 3 and 4, cost $88 per box instead of $80, for the same diaper count as the regular version in that size — an $8 premium specifically for the wider fit option.
Does either brand offer a discount for prepaying a full year upfront? No standing annual-prepay discount was confirmed for either brand's current pricing. Dyper referenced a $696 annual-prepay option in older company materials from 2019 (against a then-current $64/month rate), but whether an equivalent option exists at current pricing wasn't confirmed in more recent sources — check directly rather than assuming it's still offered at today's price point.
Is one brand more established or lower-risk to build a long-term subscription around? Hello Bello has broader retail distribution (Walmart, Kohl's, Albertsons, and others carry its products alongside the subscription), which is a meaningful signal of manufacturing and distribution scale beyond the direct-to-consumer subscription business alone. Dyper is a smaller, more narrowly positioned operation with less equivalent mass-retail presence in the sources reviewed — this doesn't indicate instability, but it does mean less independently observable infrastructure to point to.
Pricing, pack counts, and program details referenced above reflect publicly available subscription documentation and independently reported subscriber experience as of this writing. Subscription pricing, included-item structures, and program terms (particularly REDYPER's cost) have shown real variation across sources and time in our research — confirm current figures directly with each company before finalizing a subscription decision.
