Child advocacy groups generally agree that parents should create a Child ID Kit.
That kit can be made available to law enforcement if a child is lost or goes missing. It should include a recent photograph, a child's height and weight, eye and hair color and fingerprints.
But privacy experts are concerned who has access to that personal information.
"So it's not a bad idea to have a copy of those," said Eva Velasquez with the Identity Theft Resource Center. "It's only bad to let someone else have a copy of those."
Velasquez says she's concerned about advertisements she's seen where companies offer to store children's personal information. While she supports the ID Kits, she says parents need to control the information.
"The key piece is, we want parents to retain custody of that information and put it in a secure location."
Velasquez says some services will put your child's personal information on a thumb drive so you can carry it with you but warned that those can get lost.
