Hi D..
My 6 year old son, too, has severe ADHD. At 3 years old I knew it, but no one would treat him. At 4 years old, I waited three months for an appointment with a wonderful pediatric behavioralist for my son - it was sooooo worth the wait. He first put Noah on Stratera, and it did not phase him in the least. The doctor also explained to me that it was a chemical thing in the brain that was nobody's fault - I was feeling very guilty and somehow responsible. He then put him on Adderall, which worked great for well over a year, but then he started to build up an immunity for it. He then went on regular old Ritalin, and it was wonderful! Don't be afraid of Ritalin, or Ritalin based medications, because it has been around the longest and has had the most testing of all the ADHD drugs. When his doctor grew ill (and died this past October, sadly), I found a pediatrician through our insurance to start taking him to. I asked before I even made the first appointment if she would treat children with ADHD, and she does. So the new doctor kept him on Ritalin at first, but then explained to me that Concerta was Ritalin based, but lasted longer. So he has been on Concerta since this past summer, and it is still working well - however, he is on the highest dose that he can be for his size because his ADHD is so severe. The herb you asked about - Attentive Child - we have also used, and I could not see that it worked in the least. I wasted alot of money on "natural" things, and none of them worked for US, and I think it is because he is such a severe case. If you had a doctor put yours on Concerta and Straterra, I would find a new doc, because those two drugs cancel each other out. Definitely call around to different pediatricians on your insurance and ask 1. IF they treat ADHD children, and 2. how long have they been doing it?
Hope this helps...
oh, and something else to try: caffeine. When we run out of meds and have to wait for the scrip, we'll give Noah a Diet Coke or Diet Pepsi, or coffee. Caffeine has the opposite affect on the very stimulated brain.
