Well, this site TigTagz has Childrens ID bracelets that are cute, and fun for kids to wear. And get this - they are basically kid proof - tear, sweat and water proof. Disposable too. The bracelet is like a medical alert bracelet for the kids, and also can have a phone number or two on it in case they get lost, a grown up can call you. You can put if the child has an allergy to foods, or a condition like Autism, or Epilepsy. I think this is genius. Perfect for kids.
With designs like princess crowns, skull and cross bones, farms, baseball, the beach, lions, airplanes and more - your kid would not mind wearing them.
