Has anyone dealt with a fore/hind milk imbalance? All of a sudden I am seeing bright green poop. My 3.5mo is on an exclusive breast milk diet. His behavior hasn't changed so I don't think he is sick. He seems to completely drain my breast, and we only feed on one side per session, so I don't think I have an oversupply problem. I have noticed that my pumped milk looks thinner than it used to, too. Can this be related to my diet somehow?
