At what age did your baby start crawling. My son is 8 months and does not crawl. He sits fine and stands up with help. He spends time on his tummy but hates it. He gets his knees up as though he wants to crawl but then flattens them out again. I want him to crawl as I see two friends who had babies after me. One is 5 days younger than my son and he started crawling about two months ago and another friend her daughter has started crawling and she is a month and a half younger than mine. I'm happy their children are developing well, but I can't help but feel jealous that their children are doing these things and my little one is not.
