I guess we just live a different lifestyle. My wife is a full-time mom, so no daycare. The three year old dresses himself at this point, plus he and the four year old entertain each other pretty well.

I think there's also an element of once you have multiple children you just don't have any extra time. As a result, all the inessential time expenditures get cut. For instance, neither my wife nor I spend any time whatsoever entertaining our children. We don't have the time and they can entertain themselves.
