question: my son, almost three, has been passing stools with what looks like hair in it. i have long blond hair that i keep up and i notice that when he finds any hairs on the floor or couch, he likes to play with them and wrap them around his fingers and such. he doesn t seem to have any trouble passing stools...has at least 1 BM a day. and it s not an obscene amount of hair...maybe a few strands here and there. is this cause for concern?
