Hello and thank you for consulting JA,I am sorry you are finding barriers to getting the correct diagnosis and treatment. The melatonin is a good choice as a sleep aid and I am glad it is working for him. It sounds very likely that he has ADHD and needs medication. The kindergarten teacher will be forever grateful that you get this problem taken care of before school starts. Even more important, the activity level may interfere with his ability to learn and he will also benefit. Many pediatricians prefer that a psychologist make a diagnosis before they will prescribe medication. This is good practice and so, please do not feel he or she was dismissing your concerns. If it is ADHD, it is not a discipline matter and you are right to not discipline something he has no control over. Here is a website that will help you to find a psychologist: http://therapists.psychologytoday.com/rms/prof_search.phpI know it says FIND A THERAPIST but this list includes psychologists. Here is another place to look: http://www.findapsychologist.org/I hope this is helpful to you.
