My daughter was diagnosed with ADHD in 2nd grade, but I would not put her on a stimulant. I just couldn't at that young age. I waited until the beginning of the 5th grade to put her on Ritalin and it helped so much that teachers and friends noticed immediately she was better. Her grades went up, she focused for the first time in her life. I then felt guilty cuz I waited so long and could have saved her a lot of struggles. I understand not wanting to give your 6 year old daughter the medicine. You have to weigh to pros and cons. Hope this helps.
