I live in Canada, a plane ride away from my family, so I was very excited to inform my twin 3 year olds that we were going to go on a plane to see my family. It was after a few days that it struck me that they seemed nervous about it. After talking it over with them I finally figured out the problem. They thought they would each have to fly on a separate plane by themselves. How else would we all fit into one of those tiny planes that fly in the sky?
