Boogers

My son loves them. I ask him, "Why are you eating boogers?" And he says "Because I love them a lot." He snacks often with a blank look on his face like its so reflex he's not even thinking about it. I've actually seen him pick his nose and eat the booger in his sleep. I don't want this to become a lasting habit. He's almost 4. How can I curb this behavior? via /r/Parenting http://ift.tt/2dh2cS6
