What happens?

I’m just wondering what happens when staying overnight at the hospital after giving birth? I don’t have a baby yet nor am I pregnant (we’re still working on it!), but I do like to plan early, make lists, etc. I’m also just curious.

Does the baby stay In the room with you or does the baby spend the night in the nursery?

What are just some after labor things that every woman NEEDS or should know? Thank you in advance for any response.
