Disrespect

I AM FUMINGGG!!! I refuse to sleep with my baby and her dad refuses as well. We came to the consensus it is unacceptable. If you do that, cool, but I’m not going to or anyone who watches her. My soon to be MIL told my fiancé that she’s been sleeping with my daughter and not to tell me. He tried telling her it’s not okay, but he also can’t stand his ground. I’m pissed she said not to tell me. I’m pissed she’s going behind my back. I’m pissed SHE IS DISRESPECTING ME! I will not tolerate it. I absolutely want to ban her from watching MY daughter, but I don’t think that’s possible:( AHHHHHH!!! I even ranted to my mom and she said to calm down because she did that with her children. I said this MY child, MY rules. The pure disrespect...
