MIL has a habit of going out with friends on the one afternoon they look after DC2. I've said that she can go to nursery on this one afternoon a week (we get free childcare hours) but ILs have wanted to continue this afternoon.
MIL goes out and leaves her with FIL who is lovely, but is in his early 70s and I feel much more comfortable when they are both looking after her together. I've voiced my annoyance and concerns to DH but it's fallen on deaf ears and he doesn't see the problem.
The only reason we know is because our eldest child has informed us this evening that Granny is going out for the day and so won't see DC2 tomorrow. They haven't told us.
It's fine if they don't want to continue their afternoons with her, but why continue and then make other plans when there are other afternoons in the week? MIL even specified Thursday as her preferred day so it just seems ridiculous that she makes other plans regularly on this one day.
AIBU?
