Please be careful about advising anyone to use coffee or anything with caffeine--especially kids beacause the effect of stimulation of the nervous system is much much greater in kids than in adults. In other words, one cup for an adult might affect a kid more like four cups. This is not a quote from a science book, its just information I have learned and am condensing and simplefying it for breifness but it is one of the things that has been contraversial for years about the benefit or harm of giving kids who cannot concentrate coffee to help them settle down. In any case, please be careful about advising it!
