I know she has the right to have as many kids in her house as she likes, but does this just mean that I have to suck it up. Especially as I think she tells me at the last minute so that I just have to smile and go along with it.....
Would you have been more pee-ed off if she had rung the night before and said she couldn't look after DS? You don't have to suck it up but you might have to find other care for your son.
