It's my granddaughters birthday coming up and I offered to take GD, DD & her DH for a meal to celebrate.
My daughters husband has older DC who I rarely see, they were not due to be with them on this day (Saturday) but now are due to a change in their mum's plans.
I have no problem at all with them coming along, obviously. But AIBU to say whilst I'm happy to pay for DD, DH & DGD as originally planned, they will need to cover DHs older kids?
I'm not living in poverty but neither am I rich and I have next to no relationship with the older ones.
