My daughter didn't talk by 2.5 either - she had a variety of her own made up words for things, and just didn't mimic our language. We got her into speech therapy then and she has really blossomed.

Like your daughter, there were no hearing or physical impairments.

Last year we had her evaluated by a neuropsychologist for her rages - and we learned that she has ADHD combined type. As a result, I've been spending a lot of time on a board called conductdisorders.com. (which sounds scary, but is a support board for parents of kids with a whole range of challenges)

As a result, I've learned an awful lot about different neurological disorders - and recognized the symptoms you mentioned. It may be a false lead, but one I really think is important to follow through on. Shes so young, and if she does have SI or anything else related, catching it this soon will really be a boon for both you and her!
