my baby is 8 month he walks if we catch his arms and sits properly and bends very nicely if wants an object while sitting but is not crawling

A. crawling can start anytime around 6 months of age. but many times it may come to the child by 1s2 months of age also. if the child is not having any other complaints no need to worry. it is advisable not to use walker and let the child play and make attempts on its own. give regular babsy massage and diet and encouragement
