My son is now 8 and he has had a bracelet for a very long time. It is sterling silver and he really couldn’t play with it or remove it. In eight years we have only lost one and it was never found. He was four at the time and hard at play and it must have gotten hooked just right and became unhooked. He now wears a sport bracelet that can be taken off when palying sports so he doesn’t hurt anyone.
