A "Find Me Safe" kit could be the best way to keep children within reach of safety and protection when they are out without supervision.
The kits allow parents to take their child's fingerprints and a DNA sample of their hair in case they are abducted or go missing, reports the Age.
In such an event, parents give investigators the kit, which includes a recent photograph, a handwriting recognition card and an information sheet listing the child's height and weight and the position of any scars.
However, critics say manufacturers of these kits and child protection devices such as GPS trackers to monitor a child's whereabouts are simply preying on the fears of a generation of paranoid parents.
Parenting author and educator Maggie Dent said parents who did not let their children go out and play on the street or at the local park were making them nervous and anxious and affecting their ability to problem solve in later life.
Tim Cannon, Australian Family Association spokesman, said ''It's shocking to think parents would believe something like this Find Me Safe kit is necessary. It's difficult to make a judgment call that parents are getting more paranoid but they are obviously concerned that communities are not as safe as they once were."
