From all I my research I have found that preggies crave milk because we are sharing a growing need for calcium with our baby. Our sweet little babies are the vampires of calcium and iron during gestation. In addition to my milk chugging, I am also eating an organic "fruit on the bottom" yogurt a day. Clearly I/we need heaps of calcium.
I've also read that if I didn't like milk before baby, I will probably stop liking it after baby. Although, my co-worker said Yoo Hoo was her guilty pleasure during pregnancy, and still is years later. All I know is that I can drink it straight now, and I would dry heave at the thought before baby.
It may be possible that I am craving so much milk because I took Depo-Provera shot for nearly 10 years. Except at some point around year 7 it was black listed, that only lasted a few months. I was very lucky because I had none of the weight gain, moodiness or other crap side effects that most get. I just had 10 beautiful years menstruation free! I was warned the whole way through that my bones were suffering and that I needed to take calcium pills. I never did. I wonder now if in addition to the baby robing me of calcium, I am also paying for the deficiency I never dealt with?
