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.

My daughter only sleeps well in this! The sleeves are perfect for mobility while keeping her warm, and I sleep with peace of mind that she’s not warmed by plastic. 10/10! I would ask for different neutral prints, in beige tones.
