You in no way are to blame for his ED. I agree with the posts above. One thing that I wish my parents did was learn about my diagnosis and educate themselves on it. Be there for him to ask questions and by your education of the disease you will be able to help him more. Another person you may want to help treat your son is a dietician. They can be helpful in planning meals and monitoring weight. Speaking of weight, have you looked into an inpatient treatment center for him? I am guessing that he is well underweight and would need to be monitored closely as he restores his weight. Let him know that he is not alone. How did you find out that he has EDNOS? I hope you are able to get some questions answered by his pediatrician. Keep posting here will help too.
