Thank you all for your responses! I'm not sure why I'm having such a hard time figuring this one out, I think I may be slighly paranoid about having her name on it, with the whole "she may think a person is safe if they know her name" thing, but I'm not sure having just a phone number is enough, I like the "If my parents are lost..." idea, that's really cute!
Ok, I think I may use that, I need to do something before I procrastinate too much and end up with no ID for her at all.
Thanks again!!
