my son will be four right away and for about a month now it seems everytime he eats or drinks hes running to the bathroom to poop. in the morning its normal but as the day goes on the running to the bathroom to poop is more fregunt and honestly its like he sits on the toilet and a big fart comes out a long with mushy stool or it even looks like spit in the toilet and thats all there is. im concerned becuase its happening all the time, he seems to have no tummy ache but thinks if he doesnt get to the toilet he will have a wet fart in his pants. no other way to really describe it. He eats healthy, he is on a inhaler once every morning for his asthma, but i just cant figure out what may be causing this. i even stopped giving him his flinstone vitamine every morning to see if that was causing the problem. any idea?
