My guess is that it is not something that is in breastmilk, but something that is not. The stool colour changes when something other than mom's milk is put in baby's digestive system. I thnk the question should read: why isn't all stool yellow like breastfed baby's is?

Here's a question from my last baby class, which I wasn't sure how to
answer.

Why is breastfed baby stool yellow?

My sense, beta-carotene; not evidence based.
