hello my boy is 11 months old and he is crawling ly with one knee. is it something to be concerned of??

A. it's fine crawling can start anytime around 6 months of age. but many times it may come to the child by 12 months of age also. if the child is not having any other complaints no need to worry. it ixs advisable not to use walker and let the child play and make attempts on its own. give regular baby massage and diet and encouragement
