So my parents say that my baby should be crawling by now apparently they are always comparing my baby with my sister in law baby boy...they say that her baby boy started crawling at 6 months and that my baby doesnt crawl because i am to over protected with him that i should let him be but its not true i mean i do watch out when his on the floor that its clean and there is nothing around him to put on his mouth... my parents say that my baby should be already crawling and standing on his own and it worries me because my baby does roll over both sides and if i sit him he stays sitting down...my baby is 8 months and he doesnt know how to sit up by himself unless i help him. And well my baby doesnt crawl yet but i seen that he kind of drags himself and gets to where he wants to. Is it normal? What can i do to help my baby to learn to sit up by himself and to crawl? Any advice!!! Please am i doing something wrong?
