My DH was changing my DS's nappy (2yrs 4m's old) and I hear. "WTF!!!" I come in, and low and behold his nappy is filled with green loose poo. From memory he has had the odd green poop or two once before.
He is acting perfectly normal, I am not concerned really, I am pretty sure it was the sugar cookie I gave him yesterday. (The whole top of it was covered in coloured icing, dark green being one of the more dominant colours)
BUT in the instance he continues to poop green, what would the most likely cause be?
