Size Guide
Sleep Suit Bag
Please use your child's weight to find the most appropriate and safe size for them. The Sleep Suit Bag should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Bags should not be used in a 5-point harness or car seat for safety reasons.

It's the quality for me and knowing I'm putting 100% cotton on my baby is the best part! These pouches are lovely and its awesome that I can separate the legs now that he is standing. Love and totally worth it!

I got this for my son who’s learning to sleep under a blanket. He’s still getting use to the concept so I got him this style sleeping bag and it works a treat. I know he’s still warm if he’s out of the covers. 10/10
