I was fortunate enough to grow up in a house with 3 adults and 1 child, so I never suffered for attention. Now that the shoe is about to be on the other foot, I see that this ratio also helped cut down on the amount of child-induced chaos. (Not that I was a particularly chaotic child.) Even at 2-on-2, Christina and I should still be able to play man-to-man defense.
There will still be times, however, when one of us is alone with the kids and numerical superiority will be theirs. I was reminded of this fact a few weeks back when I read this story of 9-year-old twins: "The girls didn't like that their dad was singing in the car, so they pulled his hair and punched his neck." This wouldn't have made the news, except the dad then pulled into a police station to have the cops give the girls a talking-to.
I'm hoping not to have to resort to such extreme parenting measures.
