Best kiddie ID for days out?

Tomorrow we are off to a HUGE car show, and I just thought before, that in case one of the kids wanders off (Heaven forbid! :o), I want them to have something with my phone number on it.

What do you think would be the best way to do this? Texta or pen on the back of their hand? A tag on a lanyard? Or ??

We will be having a static display at the show, so should I put the business name/card on there too?

I have a couple of lanyards about, those coloured plastic key tags and other bits and pieces. Hmm, just thought one of those business card/event plastic pockets you get on lanyards would be good, but I don't know if I have even one. I really want something, as I think that one or both of them will be off with other people (friends) to give me a break, and I just need some reassurance.

Thank you!!!!

We just put our mobile number on their arm with biro.

Best thing I've seen is a little boy with a mobile phone number written on his forehead :lol:
No missing it there!

Lol Tellytubby! Not sure I need that much reassurance! I might just write on Rhino's arm, as well as giving them both lanyards with tags. They love wearing lanyards, so that'll make them feel a bit special. At least Little Miss is old enough to show the number to someone.

From a policeman's point of view don't put anything out in the open. Pin it to the inside of their clothes or something similar and show them where to retrieve it....you never know who is taking note of their name, your name or your phone number.....
