It could indicate a food sensitivity. Dairy is the most common one. Green, watery stools can also indicate a hindmilk/foremilk imbalance. My 8 month old had a few days of green, mucusy stools and I couldn't figure out what was going on. I hadn't eaten anything new and her nursing patterns hadn't changed. It went away after a few days. I never determined the cause.
