Thanks Grinity!
I have often wondered about this myself, especially after hearing dire warning that 'crawling is a developmentally necessary stage!!!!'
Mmm, yes well I had heard this prior to my DD not crawling. And yet I still, oh so naively, told myself "It's not that she can't, it's just that she doesn't want to because she doesn't like hitting her head! That, and she likes to see where she is going and to be able to carry with her hands while she moves." All of which was true. But retrospectively I know she has trouble crossing the midline, so either she couldn't cross crawl or her failure to do so has caused problems down the track.
So when my youngest started "crawling" with a symmetrical drag that looked more like a sea lion heading for water than a baby crossing the floor I had her into OT quick smart. We saw the OT at 6 months and he agreed with me that she was days from getting up and walking, but I got her cross crawling within that week and then she crawled for over 6 months. She was very, VERY like my eldest but now I think their developmental paths are diverging. In a good way. And at least in part because of the crawling.
