Interfering mom who’s not allowed to interfere?!

Ky

Okay so, my mom isn’t allowed children and cannot be left with children by herself due to an incident when my sister and I were little. I’ve told her I’m pregnant and now she’s making her plans about how she’s taking the baby on vacation, how she can’t wait to babysit. I want her to have an interactive part in my child’s life and I know that’s she’s changed, but in the eyes of the law - she can’t. How do I gently remind her? Help!!
