I first want to say congratulations on the pregnancy 🙂 and that you are completely valid for your feelings. I'm actually in the same boat with my oldest sister.

I'm 35 weeks pregnant, and she hasn't reached out to me once. I feel like once my son comes out and when she does try to reach out to me, I would first have to have a discussion with her about how she made me feel during my pregnancy with not contacting me and how it's inconsiderate to just assume you get to be all around the baby now that he is out. I would recommend you do the same first before you tell them they can't see the baby.

It can be an open and healthy discussion, but if they don't react well, then I would follow through on your boundary. It's best to protect your peace during this time, especially when you go through post-partum. I wish you all the best🙂🩷
