First off, my daughter is formula supplemented with usually 2-4 ounces per day. She has always had breastmilk poops (yellowish, curdy, "whole grain mustard" poops), until today. She hadn't pooped for 4 days, which I understand can be normal at this age - 9 weeks - but it was green and thick with lots of mucus in it. She also hasn't had any unusually high amounts of formula lately, so I don't think that is the problem.
I've also been working really hard on upping my supply, so I've been giving each breast an equal amount of time, even if she's actively sucking I'll switch sides. If I feel she didn't empty it enough (which she usually does) then I'll pump for a few minutes, but I didn't think it has been all that necessary. Until now.
Is it possible that she hasn't been able to get enough hind milk because I'm encouraging her to feed on both breasts at each session, hence the green poop?
If so, how can she get the hindmilk without block feeding or letting a breast skip a meal? I thought I'd try pumping one breast while she fed on the other, but because they're so big (E's) it's hard, plus, the milk looked REALLY watery, and is not at all like the thick creamy milk I get from pumping at the end of a session. Would pumping the non nursed on breast make the milk fattier for the next session if I continued to do this anyway?
I knew she had tummy trouble when she would NOT fall asleep last night, and when she did, it was fitful at best. Sure enough, she strained and strained and had that ugly green poop. Nothing has changed much with her diet, re; formula vrs breastmilk (if anything, the formula has decreased over the past couple of weeks).
Can a green mucusy poop be an indication of something I ate, or, given our nursing pattern (equal time on each breast) is it more likely to be a formilk/hindmilk imbalance?
