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.

This would be our 4-5 set of ergopoich sleep bags as my baby grows. Great to have warm suits for the cooler nights to keep them toasty and warm. Easy to use, clean, and best quality on the market 👌
