I saw this and wanted to share it. What a quick and easy way to provide a way for your lost child to find his or her way back to you. Especially if they are young. Just write contact information for you and cover in a liquid bandage type product. It will stay good for the day and provide emergency personnel a way to get a hole for you if your child goes lost at amusement parks, fair or other crowed place.
I have also heard of another way to do this. For you to buy a per minute cell phone just for a child to have on them in case they are lost. Have your contact information listed on the phone. You can call them and they can tell emergency personnel that the contact information is in their phone. I would personally get a phone and case that could be attached to a lanyard or belt loop somehow so it can’t get lost.
