Hi! My daughter is 4 months old (born 1 mnth preem). About 2 months ago, her stool suddenly changed from the yellow curds to brown (leaves a yellow stain though) and thick, like runny peanut butter. Around that time, I figured out I'm a hyper-lactator and started nursing for that. Baby has always had foul-smelling gas, although that has diminished in frequency since I switched how I nurse. I can't seem to ID any food I'm eating that contributes to that. She has been drooling considerably for 2 months, too. Otherwise, very happy, gaining weight, sleeping 6-8 hours at night. My other 2 always had curds, so this is really weird to me. Thanks!
