I’ve got an “icegems” bracelet – much better than the old medic alert one I had years ago… They do great ones for children too, on soft fabric straps. Also, you can put whatever you want on them, and don’t have to update a central database that charges you do to so… Mine’s got my name, date of birth “Diabetic on insulin” and my husbands mobile phone number on it..
Also save “ICE” (in case of emergency) on your mobile phone with the the number of someone sensible – apparently emergency services here in the UK and across the pond automatically look for it these days..
