I purchased the necklace
for my son (he will be 4yrs old in June) hoping that it would help him a
little. He was having issues with all three domains: Inattention,
hyperactivity, and impulsivity. Let me tell you, I didn't realize how
bad he had gotten until we had the necklace. We've only had the necklace
for 2 and a half weeks, but it's like night and day. He obeys and
follows through with most tasks, we have less issues with his
hyperactivity (but some of that is normal for his age) and he is doing
so much better with controlling his impulses. My mom was super skeptical
about it, but even she says it's helping.
