I'm 28 and have a 7 year old son, a few years after I had my son my mum had my brother who is now 5, it was all a bit weird but I have never said anything about the situation, just went along with it. We've gone together to a lot of places like on holiday etc but now my brother has started school and my mum decided to put him in the same school as my son - which is what i'm not so keen on. I've have never said anything about it and feel it's all getting too much not to say anything anymore. I have only another sister who is a year older with no children so doesn't get it when I moan about anything to do with the situation and always sticks up for my mum. Am I overreacting? I just find the whole thing strange having my mother in the playground whilst i'm taking my child to school, she got the school to take photos of the boys together without asking me (which i feel is more a thing for siblings) then we went to the halloween disco together to which I didn't want to stay as I just feel its all the other parents talk about as I've got parents constantly asking me about the situation...! Now there a christmas party put on by the parents and my mum is helping out and I said I wasn't going to it which she is now insisting she takes my son with her to keep my brother happy and won't take no for a answer it's seeming. I just want my son to have a separate school life without his Granny being so involved, I feel she's always checking on us - when we're late or resends me e-mails from the school to make sure I've seen them.
Basically how can I let her know I'm finding the whole situation too weird without upsetting anyone?
