Kids poop is funny colors from what they eat. My gallbladder never changed the color of my poop, the consistancy of it was weird for a while, but color was not off. My son does poop funny colors depending upon what he has eaten and blueberries make it soft and grey as does anything that is an odd color that he eats.
I saw that you aren't feeling well tonight. I think yours is hunger and stress and just know that he is fine and he would haveother problems if it was his gallbladder. That pain is somewhat like labor and he would not be so good with it.
TRY to live each day like it were your last
