So LO has been able to army crawl backwards (somewhat) for a little bit now. It's actually more of her trying to move forward and pushing herself backwards.

She recently has started pushing up on her hands and knees and rocking too. This weekend, she discovered how to move her knees, one at a time and together, to move them forward and she at one point moved both knees one at a time then one of her hands before giving up. I've always been told they army crawl first though. Is she still going to army crawl before crawling or is it possible she'll just skip army crawling forward?
