Every once in a while my 10 month old gets diarrhea, just once or twice in a day, then not for a month. She doesn't have accidents inside, and most of the time she isn't any more pushy about going out than normal. She eats fine, and aside from wheat free treats and the dust she licks off the floor, she isn't getting in to other things. Is this something to be concerned about? She's been fecal tested not that long ago and everything is fine.
