UUMMMMM........... I just have one kid. He isn't even 2, yet.
When I am cleaning the kitchen, he is in the next room... trying to break his current record for how fast he can pull all of the DVDs, books, and stuff from the shelves to tha floor. He's good at it. Probably only takes him about 2 minutes. When I am cleaning up that mess, he runs to the kitchen and starts emptying the drawers and the refrigerator(yes, he can open that,2). Playpens don't work. He climbs out. If I try to hold him while I clean, he struggles to get to the floor. He knows I am trying to stop the mission.
But he sure is cute.

You are gonna have sooooo much fun.
