For a newborn's first month, choose double-layer muslin cotton in simple onesies and sets with flat seams, pre-washed so it feels soft from day one. Add a muslin hat for cooler nights and a muslin towel for bath time and frequent spit-up. Wash cold and skip the fabric softener, and the fabric only gets softer with wear.
We're Vanessa and Bob, and we choose and source every piece in the Epic range ourselves. Muslin cotton is woven in a loose, open weave, so it breathes well and dries quickly between washes, which helps during the first month when outfits change often. Here's what we'd put a newborn in first.
