Our lil' Addison Cayton is 13 months old. Sometimes I like to feed him a snack when he is not in his highchair, it's just easier, and Cheerios are a favorite. We've been trying to teach him to not eat food after it falls on the floor. His latest move is to take a Cheerio, actually rub it on the floor a little, look at me to make sure I'm watching, and pop it in his mouth. Five second rule be damned.
