Hello. I Suspect My 17 Year-old Daughter May Have FAS.

Hello. I suspect my 17 year-old daughter may have FAS. She's been diagnosed with ASD, ODD, ADHD, and pervasive developmental delay. Recently, I became aware of FAS symptoms and how they present. I have no idea where to go since she's seen various physicians, psychiatrists, and therapists over the years. I'm interested in learning what physician specialty I should be seeking to get some answers. Thank you.
