Ok, so my lovely...but very intense sister in law really winds me up. I feel that I cannot say anything to her, as anyone who upsets her feels the wrath of MIL. She completely interferes when it comes to my children. She buys gifts for her parents from MY children, eg she makes calendars every year with their photos on and gives them the titles "Nanny's calendar" and "grandad's calendar".
When it was Mother's Day last year she had a photo of my son printed and put in a frame which said "nanny" on it....I think it looked a bit tacky. I refuse to give presents for Mother's Day and Father's Day from my children to their grandparents as they are not the ones who sit up with them all night when they are ill, or do anything else on a daily basis. My children's names go on the same card that our names are on, therefore the gift comes from all of us. It feels though that SIL is stepping on our toes as any personal gift like that should come from us ... If we choose to.
