Hi all, baby is 5 weeks old. As of 2 weeks ago she has been producing green poos when feeding on breast milk (both expressed and from the breast). Interestingly, she passes regular mustardy poos after her cow and gate formula. So can't be CMPA, right? She lets off explosive, watery, normally small poos when she has breast milk. Her nappies have been green every day so I must be eating something she doesn't agree with. I am just giving her formula now, but pumping to keep the supply going.
I haven't spotted any blood in her stool. Does anyone have experience of breast milk causing baby's poo to go green, without it being caused by and allergy/intolerance?
