I have a six year old son who has been having pain in his abdomen, usually at bed time so i thought it was just to get out of bed. Two days ago his stool had some streaks of bright red blood and it was floating, a pale gray color. His stool is usually pale gray to tan and occasionally floats. He hasn t wanted to eat much the last three or four weeks. I thought it was because his molars are coming in and i didn t want to push him. He weighs 43 pounds and has always been tiny, hes very active. Also possibly unrelated, for the last month he s been sleep walking and having terrible night terrors. Could the two be related...He has a dr appointment on sept 13 for a physical should i wait? any ideas.
