I agree that the length of drive isn't necessarily a concern. We've certainly been taking our child on drives at least that long. I also agree that it's really Daddy's call. They'll sink or swim and really be just fine. I thought my DH was CRAZY to take my 3 yo daughter to professional football games. She can't sit still for that long, can't walk that far up to where our seats are, can't follow the game and what were they going to do about the bathroom? You know what? They figured it out together and it gave me a nice break.
