We want time alone

How do you tell people you want time alone with just you, your husband, and your kids to bond with the new baby without sounding like a jerk?

The Godmother of both my girls and now the need baby wants to be here before her born and stay for like almost a month and I really don't want her to. Not trying to be mean but I want to be alone with my family, I don't really want anyone else around and I feel like I am going to be irritated😣

Has anyone ever had to tell someone not to come around right now and wait awhile if so how did that work??
