I Have A 7 Year Old Who Is An Extremely

I have a 7 year old who is an extremely picky eater. There is only several items he will eat, and eats them over and over. Also has difficulty with speech. Has a condition called geographic tongue. He wore a corrective helmet as an infant for deformational plagiocefaly. I read an article in the past relating to extreme picky eating and anxiety disorders. Biological mom has anxiety disorder ( panic attacks ), bipolar disorder, and depression. Bio dad also has issues; addiction, and depression. He has a wellness appt. coming up. I have brought this up before, are there anxiety disorders that would cause some of these symptoms?
