My son will be 9 months old in about a week and he still isn't crawling. He rolls around on the floor but doesn't really show any interest in crawling. How do I get him to start?

u can try by luring hom with things he likes. anyway, not all children crawl. some will walk straight away. like my kids, only 1 crawl so far. some will move themselves using their tummy which is fine too.
