My little man is almost two, and sometimes he falls asleep while latched on at bedtime. That's fine. Problem is that he has teeth. Sharp ones. When he's awake he remembers not to bite, but as he falls asleep all bets are off. When I try to stick my finger in to protect myself and break the suction, he has sharp teeth in the back too. Ouch! (used to be just gums back there) So... how do you defend yourself from the chompers without waking the sleeping toddler??
