The Sleep Suit Sack 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 Sacks should not be used in a 5-point harness or car seat for safety reasons.

It works well for my 1.5yo I was trying to transition out of night nursing to independent sleeping. He runs hot and likes to move around so this worked well for him and he tolerated it decently relatively quickly.
