You should work with a psychiatrist or pediatric ADHD specialist on medication for your son. Most pediatricians just don’t have the breadth of knowledge and experience to prescribe and manage ADHD medications.
In fact, there are two types of stimulants for ADHD: methylphenidates and amphetamines. Most individuals do well on one type or the other, but not both. So, if your son does better on methylphenidate, I’m not sure your pediatrician will ever get there, since they always use Adderall (which is amphetamine type). Plus, the statement of “a little” means your clinician doesn’t understand that dosing stimulants is based on neurotransmitter needs, genetics, and metabolism. “A little” might not make any difference, or even make things worse, for many people.
There are also non-stimulant medications available — so maybe you can try that first.
