If he has an attention disorder the Omega-3 and vitamins will not help, though such supplements are useful in general. In particulalr, Omega-3 (in the form of fish oil) promotes flexibility in the neuron (brain cell) walls and this helps the electrical activiyt of the brain to move better from cell to cell.
Now, back to the possibility of ADHD. How did the pediatrician go about the diagnosis? It might make sense to re-visit this issue. As a beginning, I would ask his teacher to complete the Vanderbilt Assessment Scale and you as well. With these results in hand, make an appointment with a child psychiatrist.
On the home front, be sure that completion of homework occurs before any recreational activity. This may enhance his motivation to focus on the work, much as your use of the timer did.
We do tend to be conservative about diagnosing ADHD in young children. In fact, though, one of the criteria to diagnose ADHD is that the symptoms be present by the time a child is seven. That does not preclude diagnosing the condition at an age younger than seven, because sometimes the symptoms are clearly evident before age seven. Parents often ask when should they consider medication (assuming the diagnosis is accurate). If the symptoms are clearly interfering with a child's mastery of normal challenges at home and/or in school, medication should be a consideration.
Thank you for your reply. In May we did fill out the assessment forms, as did his 1st grade teacher. I have seriously considered a psychiatrist. I have a friend who is a retired child psychiatrist and he had warned me to not have my son diagnosed with ADD/ADHD prior to 2nd grade. However, after spending two years dealing with notes from his teachers several times a week, I am starting to think that maybe I need some mental help! My frustration level is at maximum. He is starting to fight us on everything. First thing this morning he threw a tantrum about getting dressed for school. (before you ask, he goes to bed at 8:00 pm and we wake him at 6:45 am) I've tried putting him to bed earlier, but he only gets more upset. On weekends it is not unusual for him to sleep 11 or 12 hours.
Also, we do require homework to be done before anything else. That is a rule I was raised with and I have continued with my own children.
I believe I will start looking for a child psychiatrist in our area. I very much appreciate your response.
