My daughter is almost 3 months old and up until the past week breast feeding has been fine. I was able to breast feed and within 30 minutes pump 4-6 ounces. I knew my baby was getting plenty of food. Here in the last week I manage to pump 1-2 ounces if I'm lucky. I breast feed her for 10 minutes on both breasts and after she screams and wants more. I make her a 4 ounce bottle and after she drinks it she does fine. I have also noticed a very different taste in my breast milk. I have tasted my milk before and it was sweet, no bitterness. Earlier when she ate she had this foul look on her face and let the milk drain out of her mouth. So I tasted it again, it tasted like sour milk. And was very bitter. My diet hasn't changed. I have been starting to worry. I had my period May 15, and haven't gotten another one. I dont know what to think or what to do. Why has my milk decreased so much? Why doesn't she like it anymore?
