China with Kids: Keeping track of them...

We brought our three boys (ages 6, 4 and 2) with us on a trip to China and made them all wear laminated tags with the Chinese phrase: I'm lost, please call my parents cell phone" with our number.

We lost one of the boys in an airport (he took a wrong turn coming out of the toilets and just kept wandering) and he was returned within five minutes - with a nice phone call to tell us he was on his way.
