Hi ladies! I know this may be a weird question but I really NEED to know in order to make a decision.

One of my boyfriends sisters is in town and we would LOVE to tell them that I’m being induced Thursday that way they can stay later and meet the new Arrival. However, in doing so, he fears that his mom will tell everyone in their family and that we will ambushed with visitors that we don’t want and that his mom will try and make my delivery and our sons birth about her so we have decided to just keep it a secret but we’re considering breaking the rule JUST for his sister. My questions is, if we don’t want his mother there and she shows up, am I legally protected by the hospital with them not allowing her back to my room?
