New parents become obsessed with their infant's bowel movements (or if we're being polite "BM"). They talk about color, consistency, how often it happens and what makes it happen.
Don't be frightened by the color changes of BMs. In normal infants, BMs change color as the baby's diet changes, as the digestive tract matures, and as it is populated by new, normal bacteria. It's rare that color changes signal a digestive problem. Usually color changes just mean that there is more or less of the yellow/green/brown/orange pigments that are picked up along the way.
