good morning sir... my son is 9 months 15 days now he is sitting n rolling by himself but not crawling. how long it takes him to crawl ?

A. That’s a good milestone and achievement that your child has had in the correct age further I would like to tell you a child could learn to crawl between the age age of 9 to 10 months so now your child would actually be eligible to reach that milestone so please give us some more time
