My step-child has been with us the past few days during the day, even though it is their Mum's day. Their Mum asked if we could have them on Tuesday while she went to work because she had no childcare. We agreed to have my step-child, but I had already booked tickets for a family day out for me and my other children. We asked if my step-child's Mum wanted us to have them on Wednesday as well, assuming she had no childcare then either,to which she said yes. Again, we had prebooked tickets for a family day out. I had to then change both bookings so my step-child could come.
AIBU to expect my step-child's Mum to pay, or at least offer towards the tickets? Seeing as it was her childcare that had fallen through?
