I'm working on Monday and dp is caring for our 19 month old. He had arranged to visit his mum with her, but then he got a doctors appointment for a very minor ailment he has. He arranged for mil to have dd while he goes to the appointment - it's 40 mins from his mum's house so he'll be gone for up to two hours. Firstly I object because mil has never looked after dd and dd isn't that used to her but mainly I'm annoyed because mil currently has a broken ankle so is in plaster and on crutches and her arthritis is bad meaning she has wrist supports and struggles to lift anything - particularly a toddler. Dd is into everything and I don't think it's fair or safe for mil to be asked to look after her.
Final objection obviously being that it's ridiculous to waste so much petrol on getting a babysitter for an appointment when I take dd along to any I have. Aibu to be annoyed he's arranged for mil to have dd on this occasion?
