Hmmm... "dogmatic"??.... would you be an oldest child yourself? or a middle? or a youngest?

Just kidding!

Can't help but get the feeling that you posted with the hope that lots of people would just back up your theory, though. Usually the opposite happens here--people who disagree reply in droves!

Just to add to the discussion, I wonder, assuming your theory is correct, if teaching an oldest child requires a different approach from teaching a middle or a youngest. --JL
