Teeth!!
Cecelia has two little teeth coming in on the bottom!! They are actually quite sharp when she bites your finger. It's really funny to see her chew on things and to see her reaction to different toys that she stuffs in her mouth. My favorite is a teething toy that vibrates when she bites down on the end. When we're in the car we can occasionaly hear a little buzz, buzz, buzz from her carseat.
