There is a great article over at http://www.keepkidshealthy.com that gives some tips on parenting a child with ADHD.

Here are the first 6 tips of the 17 tips they provide...

1. Accept that there is a problem, whether or not you accept the diagnosis.  Denial will not help you or your child.

2. Do not expend energy grieving that your child is "labeled."  No, it's not fair but grieving will not make things better.  Take some time to pull yourself together -- then get on with parenting your child.

3. Be prepared to feel guilty about the time you spend parenting your ADHD child compared to the time you spend with other family members.  Be prepared for backlash you may get caught-up in as a result of other family members feeling neglected.

4. You will have to look deep within yourself to find patience.  Patience dealing with your child, patience waiting for appointments, patience waiting for test results, patience when working with the school district, patience, patience, patience.

5. In general, all children need structure.  ADHD children require more structure, routine and consistency.

6. Behavior management plans do not work overnight -- many times it takes two to three months to see results -- sometimes longer. 

The rest of the tips are great too.  And some apply to any/all kids...
