Size Guide
Sleep Onesie
Please use your child's height to find the most appropriate and safe size for them. The Sleep Onesie should be fitted around the neck to avoid your child slipping through. 2.5 TOG and 3.5 TOG Sleep Onesies should not be used in a 5-point harness or car seat for safety reasons.

- Anna R.Verified Buyer11/19/24Rated 5 out of 5 starsThoughtful design makes worthwhile value
Bought for a blanket resistant nearly two year old for chilly winters down to 14 degrees.
It fits him now because of the elasticized arms and legs, but with enough extra room in the body to hopefully accommodate another winter season. I love this value-add.
Also, I like the fabric and stretchy pockets for hands and feet.
Would recommend to others and buy again.

Super cute, looks a little girly in person but it’s very warm and our son looks adorable in it
