The Ultimate Guide to Baby Bodysuits and Onesies
The right bodysuit is the foundation of your baby's wardrobe, offering a soft, comfortable layer that simplifies countless diaper changes.
A great bodysuit is made from soft, breathable fabric like organic cotton that won’t irritate sensitive skin, with well-placed snaps and an expandable neckline that make dressing a squirming baby manageable. Poorly made versions use stiff fabrics that shrink excessively, have flimsy snaps that break, and feature awkward designs that turn a simple change into a struggle.
- Prioritize Fabric For everyday wear, nothing beats the softness and breathability of 100% cotton, especially GOTS-certified organic cotton for sensitive skin.
- Check the Closures Look for reinforced snaps at the crotch for durability and an envelope or lap-shoulder neckline to easily pull the bodysuit down over the body during messy blowouts.
- Buy Bundles for Basics Multi-packs and bundles offer the best value for stocking up on everyday bodysuits, which you’ll go through quickly in the early months.
- Mind the Sizing Baby clothing sizes vary wildly between brands. When in doubt, size up to account for growth spurts and potential shrinkage after washing.

What to look for in Baby Bodysuits and Onesies
How many onesies or bodysuits do I actually need?
For a newborn, plan on having at least 10-14 bodysuits. Between spit-up, drool, and diaper blowouts, it’s common to go through two or three in a single day, so having a healthy supply means less frequent laundry.
What is the difference between a bodysuit and a onesie?
Functionally, there is no difference. ‘Onesies’ is a brand trademark owned by Gerber for their one-piece, snap-crotch infant shirts. The term ‘bodysuit’ is the generic name for the same style of garment.
Should I get bodysuits with snaps or zippers?
Bodysuits almost exclusively use snaps at the crotch for diaper access. Full-body pajamas or Sleep ‘N Plays are where you’ll find a choice between snaps and zippers. Many parents find two-way zippers are fastest for nighttime changes.
Is organic cotton really worth the extra cost for a bodysuit?
For babies with very sensitive skin or conditions like eczema, GOTS-certified organic cotton can make a significant difference. It’s grown without harsh chemicals and processed more gently, resulting in a softer, less irritating fabric that justifies the higher price for many parents.
