Cost of having kids

CNNMoney.com has an article with the headline "Ringing up baby: What infants really cost."

I know someone who says she and her husband talked about having a baby, but only when they had enough money to afford one. These are two people who both work at good jobs.

I wish I had told her I knew exactly how much kids cost: Everything you have, ever have had and ever will have, plus 10 percent.
