Dd will be three next month and ds is 10 mo. Up until now, she has just been in love with him but recently, she started hitting him, knocking him over, pulling his hair, etc. She'll do this thing where she runs past him, does something like smack him in the head and then runs back by and tries to do it over and over. I have tried ignoring it, ignoring her and giving attention to the wounded, firmly telling her its not ok, removing her or me and brother from the situation...Nothing seems to work. Ignoring her/giving him attention doesn't seem to affect her at all. It doesn't seem to be overstimulation as it just comes out of nowhere, random times of day, all day long. If I remove her from the area, she gets all upset because she 'doesn't want to be by herself'. I just have no idea what else to do...Any further ideas?
