My baby is 3.5 months and his hair is falling a lot and the side he mostly sleeps is getting less hair , is there any problem or it’s normal ? Please suggest

A. Well actually kids have cradle cap in the scalp which is a dead layer of the skin and when it goes off it sometimes take a lot of hair along with it so once you get the scalp shaved off it is going to go away completely so you should regularly oil shampoo and brush the hair so that the cradle cap starts to come out
