I wouldn't worry. 2 year olds like to think they're helping and 'fix' things. He was probably trying to fix Daddy's finger. And they're just learning about dirty. My son throws a hissy if his booster chair or spot at the table isn't absolutely clean when he get's ready to eat. He refuses to sit down until it's clean - which is quite ironic since he ends up covering the table, himself, and his booster head to toe with food!
