It just depends on the size of your baby. My LO was 8 lbs 13 oz when she was born, and she was in newborn diapers for 2 weeks.

I agree with Artbee- totally depends on your kid. I wouldn't give any away (I mean, you can always do that later after your kid has outgrown that size, right?)
I think we went through ~8 diapers/day in that newborn period, so you could probably get more newborn diapers now if you'd like, but you'll also probably get to take some home from the hospital (they let us take the rest of the pack, and it lasted a day or two), and then you'll have a few days to make diaper runs, and once s/he is born you'll have a better idea of whether you should stick to a small pack because your kid will outgrow them in two weeks, or invest in the Costco mega-pack.
