What your baby wears will depend on the tog of Grobag Baby Sleep Bag and the temperature of your baby’s bedroom. (In the same way as you would adjust nightclothes and number of blankets). As a guide, please refer to the table below. Please remember, though, that babies 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 baby’s chest is the best indicator of whether they are too hot/too cold/just right as babies’ hands often feel cool.
