How do you sleep with a newborn

My baby is 5 days old and I’ve gotten maybe 5 hours of sleep that whole time.

I pump/feed every 2 hours as recommended by the dr. Pumping takes 20min then wake her up feed change etc takes 30min so now we’re down to an hour left. Then gotta wash pump and bottles so there’s zero sleeping. I take naps for 15-20min here and there. I’m also too paranoid to sleep when she’s sleeping unless my husband or mom are watching her.

How is everyone else doing this?
