This is my 5th pregnanacy. I have three children who were all breastfed. I've never had this problem before. With my other pregnancies, i started producing colostrum by my 33rd week at least. I am 36 weeks and so far nothing! The only difference I can think of is that I have gestational diabetes with this pregnancy. I am worried that this will affect my ability to breastfeed my baby when he is born. Can this be normal? Please help!
