Can't you still get the child id paper bracelets at guest relations? I know they used to have them. They would have the childs name and parents info written on them.
We just got back from
WDW and I must say, people are very non-observant or just plain don't care! We were coming out of Toon Town and happened to notice a little girl standing by herself crying. We watched for a minute to make sure she wasn't just sulking or something and realized she really looked lost. DH went up to her and spoke with her and yes, she was lost. Just broke my heart to see this little one so scared! Anyway, we found a CM with a walkie talkie that called security. An executive security guy came by just then and ended up putting out the ALL ALERT to everyone. We asked her if she wanted us to stay with her until her friend's family found her but she said that she would go with the man. We asked later when we were leaving the park what happened with the girl. She had been reunited with her party less than 10 minutes later. She had wandered off looking at the Halloween pumpkin outside TT and didn't know what to do. So, keep your eyes open for these little ones, because someday it just might be your child that could be lost!
