2 month old has green poop

Ashley
Breastfeeding momma's, FTM and my LOnhas had green watery poops for about a week and a half. Very few have been yellow and seedy. Should I be concerned? I've changed my diet to include a more clean diet in this time frame. Baby is still providing wets and poops and doesn't seem as though he isn't getting enough to eat. What could be the cause? Should I contact the doctor?
