God Bless You! I hope I can help. My son w/CAH is now 4 yrs old. We have never used a med braclet, nor has been one suggested to us. My docter believes the links constantly need to be adjusted, and as long as we are his primary guardians.(100% acualy besides his awair relitives.)There is no need. Plus we believe in prayer, and that God is his guardian. We have very few questions asked.
