Tracking devices

I know I may just be paranoid, but I want to be prepared for things, even if they may not be likely to happen (like, kidnapping or something).Does anyone use devices to track their children? No phones or anything since mine are under 5. I don’t know, like little ear rings with location in them? Is that a thing? Something small to tie to a shoe?I don’t really want necklaces since my kid is young enough to choke themselves with it probably. Actually, her ears aren’t pierced so I guess the ear ring thing is off the table too...Anyway, any suggestions? via /r/Parenting https://ift.tt/2XaY6jk
