I would worry with the stigma that they would look at him as a time bomb or as inadequate if it were my child that was wearing the bracelet or shirt. My mother ran a day care growing up and we had an individual who was autistic so I am very familiar with the melt down stage that you are referring to and as a child myself at the time not understanding what was going on. I feel many people not just kids but adults still haven't dealt with it enough to understand how things really are. Even if you had the bracelet the only ones that would truly understand would be the ones who have been around it personally and they would be the ones at your side trying to help or at the very least would know what was going on with or without a bracelet. Just my opinion on the matter but there is never a harm in trying either. You can always remove it if you decide to later. Thanks for the read I enjoyed it.
