missy, why waste money on things like that, what i do is get one of those plastic keyrings that you put photos on, and put my mobile number in it, i then attach it to whatever zip the kids are wearing, hey presto, jobs a good 'un
also most places like zoo's theme parks etc have child safe stickers, where you write ya number on it and stick it to the said child, then if they get lost the park office will call you
