Can someone please help me. My dd just turned 10 and she has got quite a big attitude already. The problem we are having is she is a very jealous girl. She has been playing with her friend nearly all day in her room and her friend went to ask her sister (my youngest) if she wanted to play. They then went back to her room to suggest a game to play but immediately my oldest went in a strop and said they had to get out of her room and she was really nasty about it. I tried to tell her it’s ok and they can all play together but she started shouting at me telling me to leave and saying I liked her friend better. Does anyone have any experience with this kind of behaviour? It just seemed very over the top to me and now she’s refusing to play with her friend. I just don’t get it.
