Hannah, I know that some cultures believe that colostum is not good, and the moms do not nurse until the mature milk comes in. I have heard that this is the case in Vietnam as well. I believe that my mil nursed immediately---not waiting until colostum was replaced by mature milk. I will talk to her about this and post her reply. BTW, she never said anything about this when I nursed my children. She was there for the birth of my second and third, saw them go right to my breast to nurse and never said anything. Believe me she would not hesitate to "correct" me!!!!LOL!! Aloha, Gloria Thai LLLLeader Hawai'i
