I just started giving my 9 month old daughter formula because I am pregnant again and my milk supply diminished. We've also tried out some new foods, like avocado recently. Every poo she has had since has had a dark greenish-gray tinge to it. She is otherwise very happy and healthy. I am betting on the avocado, but am also wondering if the transition from exclusively breastfeeding to mostly formula could have anything to do with it?
