Rude and possessive....?

I am having a really hard time right now, I’m currently 8 and a half months pregnant and my MIL keeps telling me and my S/O that her friend, her client, her neighbor and everyone else is going to want to watch our baby after he’s born and then carries on to give us all the reasons we are going to wanna hand off our baby....but personally I only want my mom and MIL watching him....I don’t know how to go about it and I definitely don’t want to upset anyone but he’s MINE. I don’t wanna just hand him over to everyone...I feel rude and possessive but he’s not even born yet! And I just don’t trust many people with him. What do I do???
