Third day

I have milk. Not much (yet). Every day there is more and more. The last pumping session of my first day it was barely a drop of clear on each side. Today, I sm collecting maybe a teaspoon from each and the color has changed to white. It's just matter of time before I begin to let down and substantially produce. Not confident enough yet to declare induced lactation success, but at this point I'm optimistic. The 2am wakeups for pumping may pay off afterall. Those of you who have enduced lactation, how long did it take until you finally let down and were able to get a substantial amount (maybe 3 oz or more)?
