So I’m currently looking after my grandchildren whilst their mum and dad are in London until tomorrow and yesterday evening my granddaughter, 10, had a friend round and at some point during the visit she went into my grandson’s, 12, room and broke some of his toys. She snapped off some of his wheels on his cars and snapped the arms off some of his action figures. My granddaughter was in the room with her but she didn’t say anything. I’m absolutely fuming at both of them and I sent her to bed early last night for not telling her to stop or telling me. I was wondering whether to go down to their friend’s house and giving her mum a piece of my mind or whether to leave it for my daughter (her mum) to sort out when she gets back. Would it be better for me to stay out of it or confront it with the girl’s mum today whilst their children are at school?
