My mom said she would bedshare with my baby

I told my mom I wouldn’t be okay with her bedsharing. She said it’s fine because she did it with me and my brothers. She even rolled her eyes and said, “ I know you’re a new mom and blah blah blah.” I told her I wouldn’t allow sleepovers until my son is potty trained. It’s like she doesn’t respect what I have set as a parent .I said if people have a problem with it then it’s not their choice. My boyfriend and I agree on it. He has to tell his mother that our son wouldn’t sleep over until he’s potty trained.
