hi, my baby is 7 months old girl but still she is not crawling please suggest what I need to do

A. By this age a child doesn’t even know how to sit independently where are you expecting your child will start crawling. I would like to tell you I think you had some misunderstanding after the age of six months to make your child sit with support and by the age of 8 to 8 1/2 months a child learns to sit independently after that only a child learns to crawl after the age of 9 to 9 1/2 months
