Boundaries with my mom

So I feel like a horrible person..I’m trying to realistically figure out how to draw boundaries with my extremely excited “first time grandma” mom..

Since 12 weeks when I announced to her she tries to touch my belly and I’ve told her no several times each time bc it makes me uncomfortable..even now at 28 weeks when I see her she reaches for it (so I guess the 57 times I told you before didn’t get through…okay).

At best, we have a strained relationship. I’m a textbook introvert with a very private life and mom is CNN on global blast.

A church member friend gave birth I believe yesterday and her mom sent a picture of the baby to my mom who then sent it to everyone she knows, and I know the girl who gave birth didn’t publicly announce or share her birth or baby just yet. I already know my mom will be like this with me and I’ve instructed my siblings to confiscate her phone when she comes to see the baby.

I feel like I’m being a total bitch by planning to be this way but I really want this intimate moment in our lives special and not on full blast for random people I don’t even know. My mom loves to push boundaries already and I feel like this is the best solution for the time being.

I also won’t be telling to her that I’m in labor or anything until after delivery. I honestly am not sure I even want her at the hospital..everything is a big theatrical scene with her..If baby needs NICU time or any complications, I know if she knows, then everybody in our community will know and I don’t want that.

Am I doing the right thing?
