One eating disorder that parents may not be as familiar with is Avoidant/Restrictive Food Intake Disorder. Doctors say when the eating disorder impacts a child's social life, that's when parents should be concerned.
"That desire to avoid the food or restrict the food gets in the way of they're not going to go to a party," said Dr. Ellen Astrachan-Fletcher, Regional Clinical Director for Eating Recovery Center in Chicago.
Many parents have dealt with picky eaters. it's not always a concern.
"When that kid absolutely refuses to give that food another try, and then slowly over time, they decide other foods are not acceptable," said Dr. Astrachan-Fletcher.
Doctors say they're seeing younger and younger kids dealing with eating disorders.
