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.

We love our sleep suits so having a size 4-6 is going to be great for this winter and hopefully for a few more years! My daughter is only 3.5yo but is super tall so very grateful for a bigger size as we aren’t ready to go with only blankets just yet.
