What to wear

What your baby wears will depend on the weight of Romper and the temperature of the child’s bedroom. In the same way as you would adjust nightclothes; as a guide, please refer to the table below. Please remember though, that children are all different and just as with blankets and sheets, you will soon discover what your baby is most comfortable wearing. Placing your fingers on your child’s chest is the best indicator of whether they are too hot/too cold/just right as babies' hands often feel cool.
