One of the concerns about treatments for ASD and ADHD is that parents could be incentivized to do what is convenient for them, rather than what is best for the child.
Parents don't prescribe drugs, doctors do. No system is perfect but I trust doctors and parents to do a better job than politicians and social workers when it comes to deciding what's best for each unique child.
We are talking about lifetime medication here so there is a huge incentive for drug companies to campaign for chemical solutions. Not so long doctors prescribed lobotomies for trouble-makers. Parent is correct here.
