Annoyed with visitors

My fiancé’s family literally comes over every day to visit. I told my my SO to tell them to back off a little but they don’t listen 😡 I have some kind of visitor in my house in my baby’s face every single day and I’m starting to get really annoyed by it. I just want to tell them to leave and not come back at this point! He’s 3 weeks old so they’ve been over at least once a day if not more! And they don’t even tell me when they’re coming or if they’re bringing more than one person they just show up!

Sorry I just wanted to rant 😑
