Question
My calm, well behaved and sweet two year old boy has suddenly turned into a little terror, and he is finding it quite entertaining to terrorize his big sisters things, ruining her crafts, breaking down a fort, etc. She is responding by screaming at the top of her lungs whenever he does it, and he is so high energy all of a sudden that he just gets ramped up by it all. She says things like "I hate him" and seems constantly annoyed and territorial. We have very little peace in our house especially on the winds when my husband needs to relax! What to do? They used to be so sweet to each other!!!!
