I have a 3 week old daughter and I am almost exclusively pumping. Reasons for pumping: she had some latch issues in the beginning, now sometimes latches well but falls asleep soon after or fusses and pushes breast away, is hungry again within 30 minutes after feeding from the breast, not gaining weight, husband not supportive of me continuing to feed from the breast. I pump 4-5 times a day and get anywhere from 3-6 ounces of pumped milk per session total from both breasts. She does still feed from the breast a few times a day for comfort when she's upset.
My issue is, all her poops are green and mucus-y since she's been about a week old. She also has a lot of gas and poops about 7-8 times a day. She's very fussy in the evenings, I think from the gas and digestive discomfort. Google gave me two potential explanations for the poops, foremilk hindmilk imbalance from oversupply or a food intolerance (likely dairy?). Are there any signs to look for that would indicate one issue over another? Her nose always seems congested, which makes me think dairy intolerance, but I just don't know. She doesn't spit up too much. I feel terrible because I can see how uncomfortable she is and I know it is somehow my fault
