Long post ahead!!!

Y'all, my Momaw is driving me up the wall. She lives in a different state, so she never sees me or anything. We were never close growing up, she always chose my cousin and sister. They went to the beach, my brother and I stayed home. They got laptops, we got clothes. Whatever, it's fine. Well now, she is older and she is sick all the time and is nosey, and posts shit without asking. Like when I got pregnant I didn't want to tell her bc she would post it, my dad told her and said not to post it. What does she do? She posts it. Fine whatever. Now I am 30w. I'm due soon. So I have some rules. I've shared posts on fb with the typical "don't come if you're sick" "don't take pictures" blah blah blah... She comments and says "really, are you serious? Rules?" Yes I have rules. I don't want my baby getting sick. I do not want him posted on someone elses Facebook before he is posted on mine and his daddy's. I dont want people kissing him bc he can get sick easily. And she is sick all the time.

I don't care If ahe comes and holds him and gets some pictures, but I dont want her kissing him or posting them until I do. Am I a bitch for that? Yes I am young, I am a FTM. Yes she has raised 3 kids plus grandkids, but times have changed. She is not his mother. Plus, she is a heavy smoker so she coughs a lot. Her eye sight is awful. She can barely see two feet in front of her.

How do I tell her that I am his mom and I have rules without her getting pissy and then my aunt getting mad?
