If you parent all of your children the same way, same expectations and consequences, how is it possible for them to turn out so differently? Did you really not parent them the same? I still only have the one, but we are trying for number two, and I was just talking with a parent about how their latest little one is a tantrum thrower that she can't stop. She said everything that worked for her first two didn't for this one. So what's the deal? Is it all about discipline or are there are environmental factors at work?
