My 6 year old daughter, and 9 months, is being bullied by her cousin. She has a doll which I bought her, the chad baby ava doll from argos, and she loves it very much and plays with it all the time at home.
Recently my sister's child, a boy, 10 years old, has been playing a very mean joke on her. the joke involves him finding the toy and pupeting it whilst doing a voice called "baby dave" which distresses by daughter very much.
I tried to stop my nephew and "baby dave" politely by suggesting he give her the toy back. but he continued across Multiple visits with this cruel joke. Eventually my daughter and I had enough of "baby dave" and i snapped at him. My sister overheard and has berated me on whatsapp for being to harsh with him and hasn't visited since.
Am I being unreasonable? What can I do to make sure my sister feels welcome, but that "baby dave" doesn't make a return??
