dd does a commando crawl when wanting to get anywhere and to get up and down just does the splits and lays between or sits up between her legs if you can get that..... we have been working on her crawling on hands and knees ( much easier on clothes and skin)
She really hasn't managed it but today - she got up on hands and knees and did one crawl step forward!!!
followed by a nose dive into the carpet but hey - she did one step!!!!
