Grandma problems😫

So I am really worried, my ex’s family aren’t really the perfect family.. There’s always something happening, someone knocking on the door for a fight, arguments, drinking etc.

I am currently 8 weeks and 6 days pregnant, and i’ve been worrying about when little one arrives due to my ex’s side of family wanting contact, and wanting baby to stay over at theres. But I really don’t want them to have contact with baby due to what I know happens behind closed doors, But then again they have rights as it’s their grandchild.

Am I selfish for not really wanting them having contact with my baby?

I have things running through my head like they’ll refuse to give baby back, that their smoking around baby or that there’s arguments going on.
