I think her & Chris take them out all the time to spend as little time as possible with them.
The longer the car journey, the less time they have to parent them, the more naps they take, the less time they have to parent them. They let the play centre or wherever they are entertain them so they have to do the least with them. I had an old friend who did this, she used to say it was easier taking her twin boys out all day than staying at home with them. How sad!
