I am due my 2nd baby in October. We realised early on that I was likely to be due in October half term which is when my in laws normally go away. We would be relying on them to have our eldest when I was in labour (there is literally no other option for us) so we let them know the potential due date when I was about 6 weeks pregnant.
We found out today that they have since booked the holiday and when my MIL pointed out that they might be needed to have our eldest, my FIL just shrugged and said it had been paid for.
AIBU to feel upset that they couldn't miss this one holiday (they go away twice a year every year) knowing their 2nd grandchild is due around then? It will possibly mean their only son missing the birth of his 2nd child and me having to give birth on my own (which I'm terrified about). Or am I being selfish here?
(They will be away at 40 + 2 until 41 weeks and I had my first at 40+5)
