Your understanding at his point puts him way ahead of where you were as a child.
I don't know your feelings on medicating and treating children etc, which would factor into your choice.
Our extended family has several children who definitely have ADD symptoms. They don't happen to believe in medication except in cases where the behavior is destroying the quality of life after all else fails-which for them it isn't. Everyone is different, I know, but if you want the natural approach. Here's what they do:
First of all, be sure "symptoms" aren't being mistaken for lifestyle issues. As a doctor put it, if the child has all their good nutrition, no toxins, sugars or junk, all their sleep, a calm orderly loving household, firm structure and discipline, lots of exercise, lots of love and attention, and they still can NEVER control their behavior or hold their attention, they may have ADD. But having a distracted child in a hectic lifestyle does not signify a disorder, and can be managed other ways with extra effort. Michael Phelps' mom threw her hyperactive kid in the pool. Some kids kids march to a different drummer and take MUCH more effort.
You don't want him to struggle, so wait until he struggles before you do anything potentially harmful like drugs. The long term effects are not known. I have an irregular heartbeat from a "harmless" anti depressant I took for one year as a teenager. Young children's bodies are small and vulnerable. Doctor's say everything they prescribe is safe, because that's what they're told. A year later, things can be yanked off the market for being unsafe.
Use your own experience to know what type of help you would have really needed as a child, and keep safety in mind.
Some symptoms can be allowed and understood, not repressed. For instance, people may strive to stop their child's fidgeting by any means, when the fidgeting is what helps the child focus. The moms I know with this issue homeschool, so they don't have to worry about keeping their child "still" for the school's convenience. They actually make sure they run around and extra amount during the day rather than sitting too long. Just an example, I don't know how severe your son's symptoms are.
Many artistic geniuses and functioning eccentric adults have ADD. The kids in our family with it are the wildest kids, with many challenges (and creative sparks) the rest don't have, but still amazing, happy, respectful and disciplined. It's not easy, but if understood, can often be managed. Some people say their kids need meds so they are more manageable to them and at school. It's your ethical choice. Continue to keep your child's best interest and safety first.
I would give your son all the above mentioned necessities (I'm sure you are already), and remain aware of his thought processes and needs (as you are) and have him evaluated by a high quality specialist. Then, if and only if you see your child struggling, act accordingly, being careful you are never putting your own convenience first. Best wishes, congratulations on your diagnosis being an eye opener and help, and best wishes for your son with your first hand wisdom! He's lucky!
