Infant Bodysuits & Baby Onesies

Our infant bodysuits and baby onesies are made for everyday wear, from short-sleeve kimono styles to long-sleeve options for cooler days. Every onesie in this collection — including our newborn onesies sized for the earliest weeks — is organic cotton, screened for chemical safety before it ever reaches your baby's skin.

Birch screens every fabric for chemical safety — looking at GOTS certification (the global organic textile standard), OEKO-TEX MADE SAFE, and bluesign approval before a single item enters the collection. That means no azo dyes, no formaldehyde-based softeners, and no flame-retardant chemicals on the fabrics closest to your baby's skin.

Explore More Newborn & Baby Essentials

Bodysuits are the foundation of a newborn wardrobe, but babies grow fast and need options for every season and stage. Below are a few closely related categories worth exploring — all made with the same organic cotton and chemical-safety standards as our bodysuits.

Sleep Sacks

Once your baby outgrows swaddling, a sleep sack is the safest next step for naps and nighttime. Ours are made from breathable organic cotton and come in TOG ratings suited to every season, so you can layer a bodysuit underneath without overheating.

→ sleep-sacks

Rompers

For days when a plain bodysuit needs an upgrade, our one-piece rompers offer the same easy snap-front changing access with a bit more style — great for outings, photos, or just switching up the daily rotation.

→ rompers

Two-Piece Sets

Matching top-and-bottom sets give you the coverage of a bodysuit with the flexibility of separates — easy to mix, match, and layer as your baby moves between seasons.

→ two-piece-sets

Footies

For babies who need full-body coverage without extra socks, our footies extend the same organic cotton comfort from head to toe — ideal for cooler months or overnight wear.

→ footies

Sleep Gowns

Designed for the newborn stage specifically, sleep gowns offer the fastest possible diaper changes at 2am, with an open bottom hem instead of snaps or zippers.
