packing baby's bag. help please

So I've had my hospital bag packed at least two weeks now. I had to wait till after my baby shower to pack the baby's bag. But I have a silly question how many outfits should I have packed for him? with my first I was in there for 4 days due to complications with my blood levels. And I never got to pack a baby back the first time around. She ended up coming early and my sister had them bring me preemie clothes. I don't want to over pack but I'm scared under pack.
