My older son is 23 months old. He HAS to watch at least part of Disney Pixar's Cars every day. He spends an hour lining up all of his toy cars. He begs for Matchbox cars to hold during diaper changes.
He points out trucks, tires, cars, engines, "vroom vrooms", etc EVERYwhere we go. We spend an hour after dinner watching on-line racing, mudding, drifting, etc vids (which is my favorite hour of the day).
I think I have created a monster. Did you guys have kids that were this into cars early on? Did it last? What kind of things did you do with your kids once they were old enough to "help" daddy in the garage?
