Advice/Opinions?

Soo today we were with my boyfriends mom at a cookout, and she said that she was gonna be at the hospital the day that we have our baby. She just said it, didn’t ask or ANYTHING. We already have one child together and she was born in July 2020, when no one was allowed at the hospital, and I really liked just having us there by ourselves with our baby. They’re allowing people to sit in waiting rooms and stuff now, but I have to have a c section and I just remember how horrible I felt when I had my daughter and I’m really not wanting people at the hospital bombarding me right after. Even MY own mom is going to wait until I’m ready, and I told my boyfriend and he agrees but can I tell the hospital that I don’t want extra people there?
