My son is 45 days old.. He always prefers to sleep on one side. even if I try changing his head position, he his not changing.. is this normal or need to check with the doctor.

A. Maam you have to keep changing the position not because what your child is doing is wrong or a problem is there which is that if the child is going to sleep on one side the head is going to become Flat then there is going to be a problem so when you put your child to the other side put a heavy pillow behind the back of the child so that your child cannot change the position
