question: My 16 month old son has been sick with a stomach "virus" for the past few days. The last 4 diapers i've noticed small (1/2") worm like peices in his stool. At first I thought it was related to bananas, but now there are large clumps of these reddish brown peices in his stool, thousands with each diaper change. What is the liklihood of him having a parasite?
