Meet Easton's new best friend: his thumb.
Easton's rules regarding thumb-sucking (or what we've learned by watching him):
Rule #1. Suck your thumb when tired
Rule #2. Suck your thumb immediately when you lie down in your crib
Rule #3. Suck your RIGHT thumb ONLY (but you can suck your fingers on your left hand if you want)
Easton's daddy was a thumbsucker too so I guess he is a chip off the old block.
