my 5 months old baby is not turn side by his own. is it normal? when will he start it?

A. Every child has their own pace of development. Was he a premature baby? In that case, there may be few development delays. Generally, babies tend to roll to their sides and on their tummy between 4-6 months. But some take longer and that's completely fine too.If you still have a concern, you can speak to your baby's paediatrician.
