We strongly recommend touching your child at the back of their neck or on their stomach while sleeping to gauge their temperature and level of comfort. Hands and feet are not strong indicators of core body temperature. If you feel that your child is cool to the touch, it may be best to try a warmer option underneath the sleep bag at bedtime.
The sleep bag with feet is made wide at the bottom just like our standard sleep bags so your child can pull their feet inside should they need to. Many parents also like to use socks so their kids can stay mobile while also keeping their feet warm.
