My 10 year old son, (who has been wearing Medic-Alert bracelet since he was about 18 months) has always been asked to take off his bracelet during basketball. And there are other kids that are asked to take their watches off of their wrists as well. It seens that they could really do a number on another childs face should that bracelet/watch hit. My husband and I are at every practice and game so it is not an issue at this time. I would just be sure that the coach knows what he/she should do should an accident occur, and that bracelet be very close by.
