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.

Such great quality and thoughtful design. The 2.5 tog is perfect for winter months when the bedrooms are chilly and has really improved baby’s sleep. The print is so cute and it washes really well. The smallest size fits our petite 13lb baby with plenty of room to last the whole season.
