My son who is 2, just had a bm with medium and small bright green hard stones I believe. I dont know if they are or not but they are very hard and when I washed them off they are definetly not feces. Is this something I should be worried about? Hes had loose stools for a few months now and the doctors office keeps blowing it off. They wont even take a sample. After today him having this though I am wondering if I shouldve followed my gut instinct before..What could this be? Hes not eaten anything that looks like this or is green etc either.
