On a recent stroll through Target, Millie Moon diapers caught my eye. The Strategist recently published an article saying that Millie Moon diapers are a Coterie dupe. So, naturally, I was intrigued. They claimed that Millie Moon diapers have a similar quality but with a more budget-friendly price tag. But is it possible for a cheaper diaper to be as luxurious and dependable as my favorite, but pricey, Coterie diapers? I love a good deal, so I had to find out for myself. Here's my review Coterie vs. Millie Moon diapers.
Coterie vs. Millie Moon
I've been obsessed with Coterie diapers for awhile now (read my full review here). As a busy mom of two, finding a diaper I can rely on is honestly amazing. When I switched to Coterie, two of the biggest wins were that my little ones slept longer stretches (thanks to next-level absorbency that kept them dry overnight), and I saw far fewer diaper rashes because of the absorbency and the ultra-soft, quality materials.
Another perk? Because Coterie actually does its job, I didn’t need to haul around an overstuffed diaper bag anymore. I downsized to a simple belt bag, knowing I wouldn’t need to overpack diapers or multiple outfits because I wouldn't be dealing with leaks or blowouts.
Beyond just price, I also wanted to see if Millie Moon could hold up in other key areas—like absorbency and eco-friendliness. So, I put both brands to the test.
Criteria 1: Absorbency
Quick note on this criteria: High absorbency means no leakage, no blowouts, no diaper rash, and a full night’s sleep. To test this feature, I poured water on each diaper brand, then felt how dry it was after 30 seconds.
COTERIE
Like magic, this diaper felt incredibly dry despite pouring water on it! And this is a fact: both my babies who have been in Coterie their whole lives only have had diaper rashes a couple of times and I’d equate that to them staying nice and dry under that diaper. 5/5
MILLIE MOON
Millie Moon absorbed the same as your average diaper – not instantly like Coterie, and feels damp on the touch. 3/5
ABSORBENCY WINNER: COTERIE
Criteria 2: Softness
COTERIE
OMG these are so soft! They feel like actual cloth, not crunchy disposable diaper materials. This is the #1 reason we’ve stuck with the brand time and time again – seriously you just need to feel them for yourself. 5/5
MILLIE MOON
Okay these diapers are soft, much better than your average drug store brand, but they still have that plasticy diaper feel to them. It kind of sounds like multiple layers of tissue paper crinkling between your fingers. 4/5
SOFTNESS WINNER: COTERIE

Criteria 4: Eco-friendly
Unfortunately there is no such thing as a 100% biodegradable diaper. There is a lot of greenwashing in the industry today and it's hard to know what's true.
COTERIE
Coterie diapers are made with 25% plant-based materials from sustainably managed forests. The brand reduces packaging waste wherever possible. I appreciate that Coterie is extremely transparent about its processes and materials. So while not an actual compostable diaper, Coterie is thinking about the environment and planning for a more sustainable diaper future. 3/5
MILLIE MOON
Millie Moon sadly doesn’t seem to really care about being eco-friendly. There is little detail on the sustainability of its diapers, other than a mention of being built with sustainably sourced pulp. 1/5
Eco-friendly WINNER: COTERIE
Criteria 5: Cost
COTERIE
198 diapers for $90 on monthly subscription for size 1 (8-12lb baby) = $0.45 each
MILLIE MOON
108 diapers for $30 for size 1 (6-11lb baby) = $0.28 each
COST WINNER: MILLIE MOON
So is Millie Moon Really a Coterie Dupe?
No! Coterie diapers are way more absorbent, softer, have higher safety standards and are produced in an eco-conscious way compared to Millie Moon. They simply can't be replaced. Try them for yourself now.
