Do any of your kids rock? I hope that doesnt sound strange, and I know my other girls did a little when they were alot younger, but Paige is starting to rock alot! And she grunts while she does it and will do it continuosly for a minute or 2, play with something, then do it again. It is so weird, and I hate that she's doing it. Its just not normal. Is there anything, some different sort of stimulation I can give her to lessen the rocking?
