Generally about 3 days but it can come in faster or take a little longer. Until then you should produce enough colostrum to keep baby plenty, there is no need to supplement with formula or anything.
Colostrum is produced for like the first two days then by the 3rd real milk usually is in. She may feed a lot, like every hour and some even every half hour at first to get things going and get enough. They do "cluster" feeding after the first day usually where they want to almost constantly eat. She will be fine as long as you feed her when she cries for it. Bleeding for my first, which was a csection lasted 2 weeks, for the my second which was a vaginal birth it lasted almost 4 weeks (don't know why the difference). Usually newborns are asleep if they aren't eating, they may be awake for very short times here and there and generally feed every two hours or more, but mostly just sleep, eat and fill diapers. :)
Quoting Emma1918:
Like the hospital is discharging me tomorrow :) but she is eating alot like she is on my boob so much today!! She well fall asleep when she is on my boob eating and she gets fussy when I take her off
She will probably do that for much of the first 6 weeks. :) Right now, she's telling your body to start making milk (and the colostrum she's recieving is plenty for her... it's just that her stomach is soo tiny!). She is growing rapidly right now, and establishing your milk supply... so nursing frquently is to be expected. Also expect growth spurts around 7-10 days, 3 weeks and 6 weeks... she will want to nurse even more around those times and may get frustrated at the breast. Competely normal, just keep nursing.
If you ever become concerned, count diapers. You want one change per day of life up to day 6, and then 5-6 per day after that. If she's wetting diapers, she's not starving, she's just acting like she is. :)
My baby fell out of the crib today:(
