Good reasoning

As all older siblings have asked at one point or another, why do parents have a second child when the first is so perfect? I now have the answer...

The first one got too heavy to keep pushing in the jogging stroller. At 30 pounds, Diana's not nearly as fun to take on runs anymore. However, she is pretty cute in her little running suit.

Cara will be a welcome relief in about a year when Diana gets up to 35 lbs and Cara is tipping the scales at only 20.
