Coterie vs. HealthyBaby vs. Freestyle vs. Happy Little Camper vs. Kudos vs. Millie Moon

This post is in partnership with Coterie. I only endorse products I believe in and personally use with my family.

If you’ve been researching diapers for your little one, you’ve probably noticed how many parents are now prioritizing non-toxic options, and for good reason! Your baby’s skin is delicate, and traditional diapers can contain chemicals, synthetic fragrances, and other irritants you’d rather avoid.

For me, choosing non-toxic diapers is about peace of mind: knowing I’m putting the safest, gentlest option against my baby’s skin every single day.

And if you’ve found yourself here, you likely feel the same too. But which non-toxic diapers are the best? I’m here to break it down for you comparing Coterie vs. HealthyBaby vs. Freestyle vs. Happy Little Camper vs. Kudos vs. Millie Moon

The Non-Toxic Diaper Showdown

I'm tackling this showdown the way I know best – with extensive research. I'm sizing up each contender based on the top five factors that matter most to me when picking a diaper: ingredient safety, because I want to know what's touching my baby's skin; absorbency, because nobody wants a messy blowout; softness, for that comfy feel against my baby's skin; availability, because convenience is key; and cost, because budget is always a consideration.

Quick legend:🥇category winner |🥈category runner-up | ❌ don't recommend

Criteria #1: Ingredient safety

🥇 Coterie: Total Chlorine Free (TCF), free of latex, fragrance, lotion, alcohol, heavy metals, brighteners, parabens, phthalates. Hypoallergenic, dermatologist-tested and third-party tested. They are the only brand to release a Diaper Safety Report for full transparency into safety standards.

🥇 HealthyBaby: TCF, free of parabens, phthalates, fragrances, optical brighteners, latex, and lotions. EWG verified, OEKO TEX certified, allergy certified, plastic neutral certified.

🥈 Freestyle: TCF, free of fragrances, parabens, allergens, phthalates, alcohol, and latex.

🥈 Kudos: TCF, free of fragrance, phthalates, latex, alcohol, parabens. OEKO TEX certified.

Millie Moon: Elemental Chlorine Free (ECF), latex free, fragrance free, lotion free.

Criteria #2: Absorbency

To test this, I poured 15 mL of warm water on each diaper, analyzing speed to absorption and wetness immediately then after several minutes.

🥇 Coterie: This diaper absorbed liquid instantly and felt incredibly dry within seconds.

HealthyBaby: This diaper absorbed slightly slower than Coterie, and feels wet still after several minutes.

Freestyle: This diaper absorbed decently quickly, but definitely feels wet to the touch.

🥈Happy Little Camper: Absorbency appears identical to Healthy Baby, but feels slightly less wet to the touch after several minutes.

❌ Kudos: This diaper absorbed decently quickly, but felt the wettest of all the options.

Millie Moon: This performed the same as I’d consider your average diaper – absorbed the liquid but feels damp on the touch.

Criteria #3: Softness

🥇 Coterie: OMG these are so soft inside and out! They are plush and feel like cashmere.

HealthyBaby: These are very thin – tied with Happy Little Camper, but do have a touch of softness.

Freestyle: These are soft on the outside, but the inside top sheet is a bit rougher.

Happy Little Camper: These are just as thin as Healthy Baby, but do have a touch of softness.

❌ Kudos: These feel rough and like plastic.

Millie Moon: These have a slight plasticy feel to them, like layers of tissue paper crinkling between your fingers.
