Organic Baby Clothes

Building a baby wardrobe is easier when you start with the everyday basics. Organic bodysuits are the foundation layer for newborns, and footies and rompers keep your little one covered head to toe with easy diaper access. For outings and photos, browse our baby dresses and coordinated two-piece sets, or mix and match shirts, shorts, pants and hoodies as your baby grows into a toddler.

At bedtime, choose breathable organic pajamas or wearable sleep sacks and gowns, which keep babies warm without loose bedding. Finish the look with soft baby hats, hair accessories and shoes and booties. For little ones who are potty training, our organic underwear and training briefs make the transition gentler. You'll also find cuddly baby blankets for supervised tummy time, stroller rides and snuggles.

Frequently Asked Questions

What size baby clothes should I buy for a newborn?

Most babies fit "Newborn" or "0–3 months" sizes at birth, but many outgrow newborn sizing within a few weeks. Buy only a few newborn pieces and put more of your budget into 0–3m and 3–6m. Use the age filter on this page to shop by size.

Why choose organic cotton baby clothes?

Organic cotton is grown without synthetic pesticides. When it's GOTS certified, the processing and dyeing are also restricted to approved chemicals. Because babies have thinner, more sensitive skin than adults, many parents prefer organic fabrics for the pieces worn closest to the body, like bodysuits and pajamas.

What does GOTS certified mean?

GOTS (Global Organic Textile Standard) certifies that a textile contains at least 70% organic fibres, or at least 95% for the "organic" label grade. It also checks that the whole supply chain, from spinning to dyeing, meets environmental and chemical safety criteria. It's one of the certifications Birch looks for when screening clothing.

Is bamboo fabric safe for babies?

Bamboo-blend fabrics are soft, breathable and popular for sleepwear. Look for bamboo pieces with OEKO-TEX Standard 100 certification, which tests the finished fabric for harmful substances. You'll find bamboo-blend footies and pajamas in our collection.

How many baby outfits do I need?

A practical starting point for the first three months is 7–10 bodysuits, 5–7 footies or rompers, 4–6 pajamas or sleep sacks, and a few hats. Babies go through several outfits a day, so plan around how often you do laundry.

Are sleep sacks safer than blankets?

The American Academy of Pediatrics advises keeping soft bedding, including loose blankets, out of an infant's sleep space for the first year. A wearable sleep sack keeps your baby warm without loose fabric in the crib. Save blankets for supervised, awake time.

How should I wash organic baby clothes?

Wash new clothes before the first wear, using a fragrance-free, gentle detergent in cool or warm water. Tumble dry on low or line dry to reduce shrinking. Always check the care label, since muslin, bamboo and knit fabrics can need different care.

Do you offer free shipping and returns on baby clothes?

Yes. Every order ships free with hassle-free returns, and first-time customers get 15% off at checkout. See our shipping and returns pages for details.
