In law problems

Vee • One little man, blessed with another on the way 💜🤰🏻
So my sister in law is due on Sunday with a plane d c section next week. Everyone is so excited for her and the baby and everything. So am I it's an exciting time. But I'm due June 18. And nobody acts excited. They act like I'm a nuisance whenever I try to talk about it. It's hurtful and mean. I'm a generally really nice person. I'm a force free dog trainer which means I use that kind of philosophy with my entire life and how I treat people. I don't want my kid around assholes who are just going to ignore him and put his mom down. Anyone else have to deal with rude in laws? What do I do? I try to be nice but they are just so fake it's hard.
