I work in children’s mental health (not a provider) so I’ve witnessed how distressing mental and behavioral issues can be for kids and parents and siblings. Sending lots of warm thoughts your way as you navigate getting your child the help he needs.

I’m not surprised that your pediatrician was dismissive or uninformed, GPs are generally vastly under informed in mental health issues and aren’t always the best in knowing how to handle situations where families come to them.
