Super Simple Child Safety Tip for Crowded Places Going Viral

— -- Parents, by and large, watch their kids like hawks in public places.

But things happen. And big crowds at popular summer places like theme parks and state fairs mean a child can get lost in the time it takes to reach for a camera.

A police department in California is getting big praise on social media for a super-simple child safety tip they posted last week. They suggest parents write their phone number on the child's wrist and cover it with liquid band aid, in case the child is lost or separated from them.

This post has been shared nearly 13,000 times -- and it's the second time the Clovis Police Department has shared the tip. The first time was a few months ago when it was "one of the most popular ever" tips they've shared.
