Why you’ll love our First Birthday gender neutral baby one piece:

Envelope Necklines, Because Baby Diaper Blowouts Will Happen!
The envelope neckline allows you to conveniently dress and undress with ease and comfort! Plus, the neckline design also allows you to stretch the onesie so you can pull it DOWN off your baby instead of over their head making a huge mess!
Stretch It Out For Quicker, Calmer And Less-stress Changes For Both You And Your Baby!
You can also stretch the top to pull OVER your baby’s head while getting them dressed without them getting upset by clothes scraping their little faces!
Three-snap Leg Closures To Easily Access Dirty Diapers
Because you’ll be doing clothing and diaper changes on the fly (and in the middle of the night!😵 ), the three-snap leg closure on our onesies makes it easy to access soiled, nasty diapers without having to wake or bother your baby!
