My seven week old ds has been getting very distressed when he has a bowel movement on and off for the last week. He is not constipated, there is plenty of runny poo, but it is sometimes green instead of yellow. I am breast-feeding and have tried to be very careful with my feeding schedule so that he is getting enough hind milk. I can't identify anything that I am eating consistently that may be contributing to this. Does anyone have any advice please?
