I've been with my partner for 16 months, I'm 5 months pregnant and I have a 2 year old from a previous relationship, he has a 3 year old and 5 year old from a previous relationship.
His family have a tradition where on Boxing Day they all get dressed up and a pic is taken of all the cousins, now it's all the cousins kids too. He told me on the way there that they might ask DD to sit out of 2 of the pics. They did but they also did ones with her in.
So they did a pic with all the adult cousins, a pic with all the cousins and their kids (including DD and another stepchild), the same without DD and the other little boy. Then just the kids one with DD and one without.
It made me sad at the time but DD didn't care and he said they'd probably only use it if we broke up and once we've been together longer they won't have her step to the side for any pics.
Well today his mum and and aunt posted them on Facebook and both posted the pics without DD and the other little boy.
DD did get the same present wise etc. but really it feels like she's just not welcome in their family.
AIBU to be sad about this? Should I say something?
