Friend and I worked out a system for emergencies. Our children were not to go with anyone besides their parents that didn't know the password. The password was Mermaid for friend's daughter (she's 18 now so I don't think it's important any more). Grandparents and parents and one local friend had the password. We even tested the kids a couple of times. They passed. In any given emergency we thought that should cover most situations. I know I had to use the password when I picked up friend's daughter from 1st grade when younger sibling had to go to emergency room. It worked. EdrieAnne IBSSG
