Ooooh, I know what you mean although I didn't think drool had a smell! For me it is not so much a smell, it is an action...I have a two year old who has a blocked tear duct and so his eye gets goopy and I have to clean it frequently. He will actually pick his eye and eat the goop! Ewwww! I don't know why, but even thinking about it really makes me want to gag Nose picking and eating is right in there as well Gag!
