My daughter has just turned 3, she's a pleasant girl but does have tantrums as you would expect. She has a cousin 3 months younger who is a nightmare. She isn't good at sharing her toys and he deliberately takes her toys and laughs in her face. If she wants a toy he has, she'll cry about it but if he wants a toy she has, he will hit her, kick, bite and push her over. Even if there's no toy involved he won't play or even walk nicely with her, he will push and pull her, hit her and finds it funny.
He has always been well ahead of her in his development in talking, walking etc and he's 3 kilos heavier. So he's physically much stronger and has hurt my daughter a number of times. It's really unpleasant to witness and I don't think my daughter likes him. She doesn't really have enough language to tell me how she feels. I don't really want her to spend time around him because I don't want her to get hurt or pick up bad behaviour.
It's totally uncomfortable whenever we see him because he is constantly being told off for his bad behaviour and everyone praises my daughter for being a comparable angel. She can be very hard work sometimes but she's lovely compared to her cousin.
What on earth do I do? I don’t want to be rude to my partners family but I find it so stressful to be around him because he will hurt my daughter or me. Should I speak to his Mum about it? I don’t want to upset her.
