An interesting article
I have kids on ADHD medication and when I asked our doctors about a "drug holiday," they have always told me that the only time they want the kids to take a drug holiday is if we are doing a test to see how effective the medication is...to get a baseline of how well they are acting, able to focus, etc, after being off the medication for ten days or so. But otherwise, they want them on the medication because there is never a time when kids are not learning, and as they get older and have more freedom, you really want the impulsivity controls to be working when they are out riding bikes, climbing trees, near water, and later, driving, right?
My kids take their medications to camp. They've been to camps all over the country, and it's never been a problem.
