I have a 7 year old who has trouble sleeping and also has adhd he is on 6 medicines when is it to much?

6 medications? Are these all for ADHD or are there other issues he's being treated for?
Taking too many medications in conjunction with one another can be very dangerous, especially in a 7 year old. Were all of these medications prescribed by the one doctor? If so, I really think you should seek a second opinion soon. If they were prescribed by several different doctors, you need to go to whichever you one you prefer and have a talk to him/her about all of these meds and see about cutting back.
Also, consider a change of diet and exercise to help manage your son's ADHD. It has been proven to be just as effective as medication, and in some cases has worked when nothing else will. Have a look at these pages, and perhaps consult a dietician:

I can't believe you medicate your kid at all! What seven year old doesn't seem adhd? Probably his sleep problems come from the meds. Get him off everything and start from square one, otherwise he may be heavily medicated with issues that never would have been there for years.

I'm sorry for your kid.

I would, stop giving the meds, then change his/her whole diet, and try natural stuff.

I would also recommend seeing a neurologist....instead of a psychiatrist or a psychologist....

omgosh! he is overmedicated already. see if you can find a second opinion/pediatrician. Change his diet...no dairy or wheat, and read Jenny McCarthy book "Louder Than Words"

I would definitely request non thermisol (mercury) vaccines the next time he gets vaccinated. The symptoms of mercury poisoning and the symptoms of Autism are identical.

you are born natural so stay away from those meds.
