I use who's shoes for DD age 4 with Autism...they are bright & I have heard that the cast members know what they are & are trained to look for them on a lost child. My DD would never be able to tell someone her name, my name, etc. Also, you should NEVER just "label" your kid where a stanger can readily see the name (ie. buttons, badges, stickers, even written on hand or arm)...especially with a special needs child. A stranger could see the name from a few feet away & just walk up to "Johnny" & say "Hey Johnny, your mommy sent me to get you"...and my DD would trust anyone who knew her name. That's why no names on the outside of backpacks, no personalized shirts, buttons, etc. Older or neurotypical kids can be taught a code word that a stranger would not know, but then neither would a helpful cast member...better safe than sorry. On Who's Shoes tags you cannot see the info without taking the whole tag off.
