新生児オールインワン

These fit my 7lb newborn perfectly with no bulk between the legs, and the trim layers soak up every overnight feed without leaking. I've already ordered more for the first month.

The waterproof outer layer has been a lifesaver during those explosive newborn leaks, and the trim layers still manage to hold a surprising amount. We’ve gone through a dozen changes a day without a single blowout reaching the crib sheets, which feels like a small miracle.

The trim fit is perfect under those tiny sleepers, and I love that the absorbent layers are lightweight but still catch everything during those middle-of-the-night changes. Honestly, it’s made the first weeks way less stressful, and the waterproof outer keeps messes off his onesies completely.
