Labor and Delivery Hospital Policy

I know it’s early to think about this, but was curious if people know the hospital policy where they plan on delivering their baby...

Are you allowed one support person in the room during the birth? Or more

Are you allowed any visitors after the birth?

Do you have to push while wearing a mask?

Is your support person allowed to leave if you forget something at home?

I wonder if any of the rules will change by June...
