For the past five days or so, Luke has been savagely trying to eat his fingers. He does this even after he's been fed so I know he isn't hungry. There has also been an abundance of drool and bubble blowing on his part. Could he be teething already? He does this maneuver when he's laying down where he twists his entire upper body to the side so that all of his baby drool gets everywhere and he starts grunting and the finger-eating commences.
He's also been pretty fussy, which is completely out of the norm for him. Both boys are usually fussy in the evenings, but Luke has been fussing in the afternoons as well. Any opinions on what could possibly be going on?
