Hi K.-
Have you considered an appointment with a 'developmental' pediatrician?
Reston Pediatrics had one some years ago...her name was Dr. Polly panitz...she went on leave as she had an 'adolescing' son with some issues...but maybe now she is back in practice? She was the best...up to speed on very complex medical issues my daughter had/has...but also extremely focused on her over all development...
This was some years ago...
best luck!
