SIL is having a big birthday party tomorrow night. It’s family and friends and has been booked for ages at a local venue with bar, disco.
Family are coming from different parts of the country, with some staying at other local family members homes and some staying in hotels.
We have 2 DCs, so SILs niece and nephew. DD 10, DS 7
This morning she’s nonchalantly messaged me saying oh no, just found out after speaking to the venue that kids aren’t allowed. I asked her weeks ago and she said they were! My DC are so excited to celebrate their aunts birthday and see their cousins/other kids from extended family, and now they can’t go and she doesn’t seem to give two shits! They’re going to be gutted.
Cousin (in law) is driving over after school tonight to stay at ours with her kids for the weekend, and SIL hasn’t even bothered to tell them that their kids are now not invited.
I know I’m not being U, but what are we supposed to do? Or maybe I am being U as it’s her party so she can do as she pleases.
