I am so happy to see you are so supportive of your child's learning journey and have embraced the diagnosis of ADHD. I'm a nurse practitioner and can not say enough times that medication is only part of an answer. It seems that in your child's case that their vision was a big deterrent and may even have contributed to the ADHD diagnosis. Keep being supportive and your child will succeed beyond anything you could have expected.
God gave him to me to take care off and love him and that is my purpose in life.
