Yesterday my daughter alerted me to her stool looking funny. It was the desired color and consistency, however there was white solid looking piece or possibly 2 pieces in it. Could this be mucus? It really was almost solid and not jelly-like or stringy as mucus has been in the past and also looked very white. It did not resemble any kid of undigested food either. Best description on appearance is a chocolate cookie with a macadamia nut in it, sorry if I'm ruining anyone's favorite cookie with that description.
