Needs support to sit
My baby will soon be 9 months old and still needs support to sit. He has just started to put his hands on his left and right side to hold himself in the sitting position. I took advice from a doctor. He told me to have a scan for his cerebral part and to do some exercises with him. However, I do remember that he started holding his head a bit late. Does that mean there is late development? Please advise.
