Backstory is my kids DF (my ex) was a bit crap, had them once a week for 1 night, never took a day off if they were sick (even though he worked closer to school than I did) rarely helped with childcare during school holidays, never helped pay for any childcare while we both worked and gave bare minimum child support. His family never helped with kids and if he did ever take them on holiday in summer it was always in term time which was no help at all in terms of 6 week summer holidays.
Now he has a child under 5 and expects our older kids (over 16) to be his free childcare for their sibling all day during the holidays. Neither of my kids drive yet so there is a lot of back and forth with picking them up and dropping off. One of my children chose to say no thanks to it this year and under pressure from ex and older child has now given in. I was dragged into it when one of my kids was pressuring the other one to agree and now they aren’t speaking to me because I said he was being a CF.
AIBU to think you book your own paid for childcare like the rest of working parents have to? Just because you are family doesn’t mean they must babysit for you to save money?
