i'm a biter, not a fighter....

caleb bit brynna on the arm today...don't know what provoked it other than maybe it was because my mom was carrying her. he occasionally bites my mom's knee, but other than that biting hasn't been a problem...yet. tonight he bit my arm unexpectedly as i was playing around with him. i hope biting doesn't become a problem for him. after he bit brynna he knew he did something wrong because my mom yelled, then i pinched his cheek and bit his arm back. he cried, but at this age i don't think he truly understands yet. we'll see if this continues...brynna has a couple red dots on his arm where he bit her, but she didn't really cry much when it happened.
