I have raised four kids, and I was a foster parent for 15 years. One of the things that I came up with when taking kids on day trips was to write my cell number on their arms in ink. That way, if they got lost or separated from me, they could have someone call me. They didn't have to worry about losing a piece of paper, and it was a little extra insurance with little ones who were too young to talk or learn my phone number!

When my children were young, I used to dress them in the same color clothing anytime we would plan to be out in a large crowd. We all know how little ones can get excited at theme parks or even in a crowded mall and almost disappear before our eyes.
This is more of a safety tip than a thrifty tip! With back to school, here, don't label your child's belongings with his name where strangers can see it. Put his name inside his things. If a small child is addressed by name by a stranger, the stranger seems "known" to the child.
I'm a foster mom and mom, and when I take kids to someplace with lots of people or opportunity to get separated, I write my cell phone number in ink on each child's arm so if they get lost, they can have someone call me!
