I let my 15-year-old fly home alone from Europe. It didn't go smoothly, but I'm still glad she earned the independence.

Courtesy of Jamie Davis Smith When I booked an extended-family trip to Europe, my teenage daughter complained it was too long. I agreed to let her fly home early by herself, even though I was nervous and reluctant. She forgot her passport and faced delays, but she got home safely. Most summers, I try to pack in as much travel as possible with my kids. My children have dual citizenship , and it's important to me that they spend time in Europe and connect with their roots. I enjoy showing them the rest of the world, too. In past years, my kids have had fun traveling from Rome to Warsaw or Seoul to Tokyo.
