After 2 weeks of blockfeeding, my LO (6 wks) is still having green poop. My blocks are 4 hours long, and she usually nurses 2x in that period. I make the blocks longer at night since she usally sleeps a little longer. Should I lengthen my block times? My biggest concern is that since she was 2 mo. preemie and is still sleeping most of the time, that she will "wake up" in the next few weeks and my supply might be to low. Does this seem like a ligit. concern or am I worried about nothing? I have thought about waiting it out until she wakes up more, but I am worried that even though she is gaining weight now, if the imbalance goes on to long she could start to lose weight?
