We are eliminating Soy and Dairy because of specs of blood in the poo. I started with dairy and it got a little better then took out soy and the amount of mucos and green poos went down big time. The amount of blood went down too. We will go several days with none then I slip up and have a small amount and they return a little but they have definately gotten better. I was told that it can be anything. I am also avoiding tomatoes and orange juice as of today because of a red bottom.
