My good long time friend has a 21 mo. old boy and he is very aggressive. I'm not sure how to handle the situation when he hits my dd(23 mos). My dd looks at him like he's crazy and I don't think she understands why he would hit her. I console her and his mom tells him no hitting but he keeps doing it. Then what about when he always wants anything and everthing she's playing with. The thing is she seems ap , still breastfeeds at night and they coslept for a while. Is this typical toddler stuff even with ap families?
