Breastfeeding mommies

How long did it take after birth for your breast milk to come in, not the colostrum? I'm sure it varies but I would like a general idea. I tried pumping to see what would come out because it's been 2 days and it's still colostrum. I can't wait until the milk comes in so I can see how much I'm giving him.
