My dd is 2.5 yrs old and gets extremely hyper to the point of hurting herself because she's not concentrating on what she's doing. I'm sure it's normal but just wanted to check and to get advice on how long it lasts? She constantly talks all the time, to anyone, and will go up to strangers and talk away to them. She runs all the time and never ever listens to what we tell her to do. She has always had a lot of energy but it seems to have gotten a lot worse recently. Just the terrible 2's??
