When Nora was born, Jim was just 19 months old, and still unable to communicate other than with the most basic words (ba-ba, da-da, na-na). But we could tell right away that while he liked his new sister, he was a little jealous when our attention was focused on her needs, instead of his, as…

It’s pretty obvious to most people that the two shoes in this picture are the same size: But if you actually took a ruler to your computer display it would show that the image of my right shoe is nearly twice as wide as the image of my left shoe. Young children will mistakenly say…

When I was in elementary school, we had two recesses every day: 20 minutes in the morning and 20 minutes in the afternoon. Plus, we had a 30-minute lunch period, and as soon as we finished eating we were free to go outside and play until the bell rang. So I was a little surprised…
