Hi Mayelynn,
I had colostrum 3 weeks before baby was born, and my milk came in on the 5th day. I was quite concerned too cos baby did not poo for the first 3 days at home with us, but she was taking in colostrum so I wasn't too concerned. She finally made her first poop at home only after the 4th day at home with us, and its been non stop after that! Don't worry, persevere, you milk will come in soon. When it starts to come in, latch bb on frequently so that you don't become too engorged. The amt you pump out will be quite little as well, but don't worry, this will increase soon.
