To cut a long story short, SIL and DN visit my house. A lot. Even when I am not in (they have a key, as does MIL). SIL and DN have own house in same town.
MIL picks up daughter from school and they all congregate at my house. Am currently 36 weeks pregnant and regularly come home to house absolutely ramsacked, no food left in cupboards, dishes everywhere, toys all over the floor etc etc.
I work full time, as does DP. AIBU to feel annoyed at the fact that I have to clear up after, and shop for, people who obviously have no consideration for the fact that I am physically struggling quite badly?
