Matthew, I took your comments and those of others as I believe they were meant

and I don't believe anyone here was truly condoning the biting or beating of children.
But, since the issue has been brought up. In my experience, if a parent cannot control his/her own child to begin with anything you say to the parent falls on deaf ears. They won't suddenly learn how to parent because someone gives them a suggestion.
As far as what was learned? I believe the child learned that he better pay attention to the rules put forth by at least one adult.
