I'm not sure if I'm being ungrateful or overreacting so I'd like some advice please. Every school holidays my mother in law (or ex mother in law as of last year) very kindly takes time off work to look after our children. The only issues that I have is that she takes them to McDonald's for lunch every single day. So next week she has them for 2 weeks, she used to let them have a happy meal but now says they're 'too old' for happy meals so gets them a full medium adult meal each, a milkshake AND a McFlurry! They are 7 & 9.... I have never said anything in the past as appreciate that she's looking after them for me and 2 weeks childcare for 2 children costs a fortune so don't want to seem ungrateful. Do I say something to her or just let it go and think that 2 weeks isn't going to do them any harm?
