So Bailey will be 9 months old next week and she has yet to even attempt crawling, I have been reading some of the milestone online things as well as development books and they all say that she should either be crawling or learning to walk by now. She has absolutly no desire to crawl or even be on her tummy long enough to want to crawl. We are not the kind of parents who carry her all day long, she does well just playing on the floor by herself, we carry her from room to room, but should I be concerned she doesn't want to crawl. We can however get her to stand on her own if we prop her against a couch or something, but she is not able to pull herself up. I know that every baby develops diefferently but it just seems she should be farther along by now.
