Hello My 4 year old son has recently had a lot of green poops. He has usually one poop every day sometimes every other day. Lately he is very tired all the time. He sleeps all night and the next day he looks exhausted. He normally is a high energy child. It seems to be the last couple of weeks. He is about 36lbs and sorry not currently sure of height. he has not really had any medical issues. He has some seasonal allergies. He sleeps about 10 hours a night. He takes a multi vitamin. Let me know if you need more info.
