I just want to encourage you to try some interventions in addition to medication. Consider for example taking him to a functional medicine practitioner with adhd experience who could guide you towards dietary changes and supplements that might help. The other two big interventions that I would recommend is lots of outdoor time, lots of physical exercise, and strict limitations on, if not the elimination of, screen time. So many parents complain about the difficulties that screen time can cause but then they act as though they’re somehow required to allow it. We as parents don’t have to follow the culture on that. Our children will find other ways to occupy themselves. Finally I would recommend looking up some guided meditations for him online. Giving children training in mindfulness can be very beneficial.
