When I was a child my parents bought me an SOS talisman with my details within, good idea at the time and as a parent I would have done the same. These days I am more complacent and don't really carry identification as such but I do have a card in my purse which states I am diabetic and all my relevant details, (probably dated!) The 'things' worn upon me have stopped, I don't know if that is a good idea or not so I would be interested to hear of what others do too!
