My brother's DS is 4. DB isn't with the mother of his child. Things are very difficult and he is going through court to improve access. DB is very worried about his DS's development in relation to what is going on at home with his mother who is the resident parent. She has some mental health issues exacerbated by her domineering family.
Lately DN has been showing some behaviours which are worrying my DB. He has 'acted' out spiteful things on his loved teddies. Like pinching, and twisting their arms. He asks if it would hurt them. I can't remember exactly how DB put it but he said that when asked, DN said it was a good idea to hurt them.
DB is concerned either he has seen self harm from him mother which she is perhaps unaware of or even worse, is being taught morally dubious behaviour (which is happening in other areas).
Does anyone have similar experiences with children acting out spitefully? I wanted to reassure DB that perhaps it is 'normal' but at the same time, in light of other things going on, I don't think he should ignore it either.
