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.

My son loves it!
- Damla K.Verified Buyer11/26/24Rated 5 out of 5 starswe love it
This is our second one. Our daughter grew out of the smaller size.
It is warm (but not too warm), soft, comfortable, easy to wash & dry in a tumbler.

We absolutely love this sleeping suit and have used it every year for 6 years, upsizing every year. Devastated to find out that they’re not making bigger sizes anymore. There is nothing like this on the market for bigger kids.
