If it's free, get it, whether he wears it or not, it'd be nice to have available if he goes on a trip or is away from mom and dad for very long. I've thought about getting one, but typically they're fairly expensive and I wouldn't wear it much if at all. I would say be sure the teachers at school and the workers at daycare etc. know about cf, and not worry about the bracelet unless diabetes or something else that could flair up accutely and need medical attention immediately while he is away from his parents. Only cf technically probably qualifies for a bracelet, but I'm not getting one right now, that is, unless anyone could get in on this free medic alert bracelet thing <img src="i/expressions/face-icon-small-wink.gif" border="0"> lol
