How soon?

How soon did you/or are you packing your hospital & diaper bags?? I'm 30 weeks and it still seems early but I always like to be prepared. I know some women don't really bring anything but I definitely want to make sure I have the things I want with me for my stay. I'm also suck on when to start setting things up. I haven't even prepared baby boy's room 😩 any recommendations on time frames?
