#AskTheExpert my boy baby is 7 months and 7 days old. why is he not able to sit or crawl well on his own

A. A child learns to sit independently between the age 8 months to 8 1/2 months mostly apart from that also I’m going to tell you that a child learns to walk independently between the age of 12 to 17 months crawling happens between the time of 9 to 10 months so currently there is no delay in the process anyways
