My honest answer as to how I would make a long trip with a young child is that we would take a Greyhound bus. Then I'd be available to interact w/him instead of having to make driving my top priority. I don't think that is "unrealistic" as my 4-month-old already behaves much better and acts much happier in my lap on a city bus than in his carseat when the only other person in the car is driving. I think that being available to my child is much healthier and more fun than sticking him in front of TV while I cope w/the stress of driving and feel jealous that I don't get to see the movie.
As for how I would cope w/having 7 children, my honest answer to that is that I would not have 7 children.

My inability to cope w/that many kids for an extended period in a stressful situation is one of the reasons.
If making life choices in accordance w/my values and being able to explain why I think those are good choices makes me "judgmental", so be it.

I realize that there are families who are forced into circumstances they would not have chosen and that these circumstances may lead them to (among other things) decide that watching movies in the car is a better choice than the alternatives realistically available to them. I don't say, "Look at those horrible neglectful parents" when I see a van with a TV playing, because I don't know the circumstances. But I am disturbed at the GENERAL TREND of regarding such things as a good idea.
