DH's DB's Wife. She's always been a very difficult person, lives very close but minimum contact to every couple of months (usually a birthday). DH and DS invited there this weekend for and arrived after lunch.
After a few hours SIL proceeded to cook dinner (basic oven food) for her, BIL and their kids and left DH and DS out, even set the table just for them. When DH asked if there was any food for DS she got angry and blamed BIL for not telling her they were staying for tea, wasn't apologetic and didn't see what the problem was. DS is only 2 so doesn't eat much. Whenever we see DN's we are always generous and have never done anything remotely similar.
I'm not quite sure where to go from here and would welcome advice on how to handle it. I want DS to have a relationship with his family as he loves his cousins but it breaks my heart to think he would ever be made to feel left out or not equal to her kids. BIL did apologise to DH and seemed embarrassed but every time he ever speaks up for himself SIL just shouts and screams at him.
I found out this morning that SIL did exactly the same earlier this year when my Mum took DS round there at dinner time, my Mum knew we already had a fractious relationship so never mentioned it until now.
I can't imagine growing up and having an Auntie that made me feel inferior to my cousins, and whilst DS is still young, I feel we need to decide what to do in the future before he starts getting old enough to notice. This is DS's only Auntie and Uncle.
