Hmmm...depends where you are. At my hospital in the US, someone who has a completely natural vaginal delivery can go home in 6 hours. Someone who gets an epidural stays 24 hours, but this is more to make sure baby is okay before discharge. If you are positive for GBS, the pediatricians like for you to stay two nights as most GBS-related pneumonia symptoms show up within 48 hours. If you're in the US, I would talk to your OB as they're the ones that discharge you. They'll let you know the soonest you can go home.
