AIBU in thinking this is really off?
A relative of dh's (it is his maternal grandmother's 1st cousin's daughter in law!!!!!) is having a 50th birthday party in a few weeks. It is about 1.5 hours drive away and an adult only party. We can't ask any of dh's family to babysit as they are obviously going to the party. My parents will have stayed at our house for 6 days the week before to look after ds and dd whilst dh and I are in the states, so I don't want to ask them to come over (they would need to stay the night) as they will still be recovering . Both our usual babysitters are studying for school exams so aren't working atm.
So anyway.......
We were at IL's at the weekend and I said I didn't think we would be able to make it our perhaps dh would go on his own, as we had nobody to care for the children. SO MIL suggested we invite my sister and her dh plus children to come for the weekend and get them to babysit. I thought that was totally out of order. MIL thinks I am being totally unreasonable, and is now accusing me of being deliberately awkward and trying to spoil the party for everyone.
WOuld you ask someone to drive over 2 hours on Friday night with 2 small children to return home after lunch on Sunday, and ask them to babysit 4 children on Sat night (with you leaving at about 6pm to return after midnight)?
