I do not know what to do anymore. My little girl, 2 1/2, is a case of text book behavior - hitting and pushing 11 month old brother, being difficult and clingy with me, aggressive in the playground, wanting to be a baby ('I want mama booby'), you name it. I try to be very patient and give her lots of hugs. But it got worse recently as little brother started to crawl and infringe on her space more. Any tips? I am desperate.
