An ideal situation is to be given a couple of "practice kids" before having any for real. It would be kind of like bowling a few frames for free before you start keeping score. I used to think having a dog would be adequate preparation for parenthood, but you know, it's not really the same. You can't just leave out a bowl of water and trust that your children will entertain themselves by licking their stomachs and chasing squirrels. Also, if a child does something wrong, like color all over the walls with a permanent marker, you can't just whack him/her on the nose with the Sports Section and say, "Why did you do that?" It is not an effective deterrent.
