Do your family a favor and go for it! We were skeptical. My 8 year old son has pretty severe ADHD. It took about a week for my husband and I to “think we might be seeing a shift” and another week to know for SURE that this had been an excellent purchase. Frustration tolerance, flexibility, and general mood have all improved. It’s now been about a month, and we’re still amazed at how many of the moments where we steel ourselves expecting the explosion now dissipate before a full meltdown. Not a cure-all of course, but a powerful support in allowing our son a chance to experience a little more go-with-the-flow. Our whole household has benefitted.
