my baby boy is 9 month 1 week old he is crawling on her belly using his arm but still he is not sitting independently , is it normal? pls suggest what to do

A. Ma’am crawling this way is normal initially now the child is going to take up the proper position and learn to crawl between the time of 9 to 10 months complete right now child is unable to sit independently then it can consider it as a dealy so you can consult your doctor one time maybe there is some deficiency or anything that would be clear after getting the child exam
