So my sister has no children, she has pcos and married a man who has a vasectomy. I have 2 with one on the way and I'm getting so tired of her comments. This baby wasn't exactly planned but we weren't using protection so it wasn't unplanned either. When I told her, she assumed it was an accident and said "to make everyone's life easier I'll take this one". Like my kids are up for the taking?

I have no idea how to address this because she is very sensitive with a woe as me attitude. My daughter looks just like me but my son has blonde hair and blue eyes so she tells everyone who will listen that he's her kid. Literally every time we talk she says something about "her" kids and how much she wishes to be a mom.

I understand on one hand but my sympathy is limited because she knew she wasn't going to have kids when she married her husband. I can't just tell her that it makes me uncomfortable because she will say she's just joking...that's her go to whenever I try to have a conversation about anything with her.

Any help or advice is appreciated I'm just completely at a loss and I really don't want to continue fake laughing or having awkward silences when she says these things.

Edit: yes she has pcos but her husband has 3 grown children and does not want any more. She knew this before marrying him. There was never a chance that she was going to have a kid because he doesn’t want any more.
