On St. Patrick's Day, Ellie woke up and decided she wanted to roll EVERYWHERE. Under the futon, under the coffee table, inbetween the speakers and the tv. I'm really proud my daughter has decided to be mobile. She gets frustrated she can't crawl yet; she rolls on to her stomach, screams, then drops her head to the floor and cries. Still, this is the first step towards crawling so she may not skip it afterall.
I mentioned this to our pediatrician. (By the way, Ellie was 12 lbs 1.5 ozs on March 18) I said that her physical therapy evaluation is next month and that she does not sit unassisted to the point where I trust her just yet. He said not to worry, he doesn't expect babies to sit up on their own until AFTER they become mobile, because thats how they build up muscles. He also said he doesn't expect to her to become mobile (crawling) until at least 9 months at the earliest. And finally he said not to worry about the evaluation because she's only "at-risk" and there is no actual problem at this stage.
