Diaper Materials Comparison: Bamboo Vs. Plant-Based

Hello Bello Diaper

One of the biggest differences between Hello Bello and Millie Moon is the actual diaper materials used. So let’s do a deeper dive on how plant-based cores compare to bamboo fibers.

Hello Bello’s Plant-Based Cores

Hello Bello’s diaper cores contain plant-derived materials like:

  • FSC certified fluff pulp from sustainable forests
  • Super absorbent polymer crystals made from plant sugars
  • Plant-based leak barriers and outer lining

Benefits of plant-based cores:

  • Renewable and biodegradable materials
  • Effective moisture absorption and containment
  • More affordable pricing than bamboo
  • Soft feel but not as silky as bamboo

Millie Moon’s Bamboo Fibers

Millie Moon uses bamboo viscose fiber containing:

  • Viscose from bamboo cellulose
  • Polymer absorbers
  • Outer TPU lining

Benefits of bamboo viscose:

  • Hypoallergenic and antimicrobial properties
  • Ultra soft, silky feel against skin
  • Highly absorbent and moisture-wicking
  • Flexible and stretchy for comfy fit
  • Naturally breathable and temperature regulating

Downsides of bamboo:

  • More expensive than plant-based materials
  • Takes longer to fully dry out

So in summary, Hello Bello’s plant-based cores absorb well but can feel more “plastic-y” while bamboo offers superior softness. However, bamboo costs more and takes longer to dry. Consider your priorities in terms of feel, absorbency, eco-friendliness, and budget.

Absorbency Comparison

Now let’s compare how absorbent Hello Bello and Millie Moon diapers are:

Hello Bello Absorbency

  • Features an “ultra” absorbent core
  • Quickly pulls moisture away from skin
  • Plant-based polymers trap liquid to prevent leaks
  • Works well for heavy wetters and overnight

Millie Moon Absorbency

  • 12-16 layers of bamboo fibers
  • Ultra absorbent polymers for moisture locking
  • Stretchy bamboo contains messes well
  • Works great overnight with no leaks

Absorption Bottom Line

While both brands offer stellar absorbency, Hello Bello seems ideal for very heavy wetters given their ultra absorbent cores.

But Millie Moon’s leak protection is still excellent.

For most babies, both will sufficiently contain messes.

Sizing and Fit Comparison

Let’s also look at the sizing and fit of these two diaper brands:

Hello Bello Sizing

  • Goes from size Newborn to size 6
  • Fits babies from 0 lbs to 35 lbs
  • Run large, especially newborn size for smaller babies

Millie Moon Sizing

  • Goes from size Newborn to size 5
  • Fits babies from 0 lbs to 33 lbs
  • Run small, so some babies outgrow early

Fit Takeaway

If you have a very small or premature newborn, Hello Bello’s larger sizing may fit better initially. But some babies outgrow Millie Moon early given their smaller size range. Check measurements when choosing sizes.

Pricing and Affordability

Pricing is another key difference between these brands:

Hello Bello Pricing

  • Starts at just $0.25 per diaper when you buy bulk packs
  • Offers subscribe and save discounts for scheduled deliveries
  • Budget-friendly pricing, especially for an eco brand

Millie Moon Pricing

  • Around $0.27 per diaper across all pack sizes
  • No subscription discounts available
  • More expensive than Hello Bello but typical for a premium diaper

Pricing Bottom Line

If you want the lowest cost natural diaper, Hello Bello is the budget-friendly choice. But Millie Moon’s pricing is reasonable for its luxe materials.

Availability and Convenience

You also need to consider where you can buy these diaper brands:
