Toddlers vs. Teens

I'm wondering if there is a study that's been done showing if a child's behavior as a toddler is any predictor of their behavior as a teenager. Actually, I'm sure there is such a study, I'm basically terrified to find that there is a link, so I have chosen not to research the topic! It's been quite a weekend in our household. Everyone has been fighting a cold so there has been a lot of whining, runny noses, breakdowns, and the like. However on Friday as I was preparing lunch for Mallory and I, I caught something strange out of the corner of my eye. As I started to close the refrigerator I noticed something in the door compartment. Hmm, a dog kong, just what I would have expected to find there. Who doesn't keep dog toys in their fridge? Then on Saturday I caught guess who, Miss Mallory, hiding yet another dog toy in the refrigerator. I guess it's the one place she can get to that they can't. At least if they are in there I know Michael isn't chewing on them! Now, I'm just waiting to find Norman opening the refrigerator! Then there's today, Mallory and Michael have been playing in the hallway with a large exercise ball. Then I can hear her going up the stairs, I tell her to come down, to which I receive a slur of who knows what. Then a few loud booms and a crash and screams! Yep, she threw the ball down the stairs, somehow thinking that her 9month old brother laying at the bottom staring up at her would catch it! Needless to say, he didn't! So the ball not only hits him, but apparently it hit him, hit the baby gate and bounced back enough so the gate could fall on him and then the ball could bounce back on top of the gate. What a pile of debis!
If you know of any good boarding schools, I'm taking suggestions!
