Ok not as bad as it sounds. I usually do give her snacks etc but they have dinner/tea a lot later than us and she pops over to visit ds right at the time I'm cooking and getting ready to serve our meal.
She asks me for "something to eat and drink". (Usually asks for this for both her and ds). Yesterday I just said "No, im sorry. We are just about to eat tea and I dont want ds having a snack before so he will eat his tea".
Is it so unreasonable to refuse her?
