First of all, I have read what I could find in these forums as well as online, youtube, google, etc.
My ASD son is 7-1/2 years old, and was finally diagnosed at 6 with ASD after a series of tests starting from the time he was 18 months of age. Under old classifications, I am told he would fall into the "High Functioning" catagory. He gets straight A's and B's in school, and his main struggle is with social/interpersonal relations; be it from carrying on a full conversation with new people to shutting down from overstimming in busy places with too much noise. He wears noise-suppressing headphones at school most of the time to negate the latter of the aforementioned issues.
The main issue we have is when he gets a cold. My exwife (his biological mother) always had a horrible immune system, and like mother like son, he tends to get colds quite easilly. I keep him in as good of health as I can with his diet, but like many ASD persons, he is a very picky eater. Thankfully, he loves oranges, so keeping him topped up with vit C is not an issue.
After attempting everything I have found, I am still unable to teach him how to blow his nose. I understand this is fairly common and will generally get better in time, but I am looking for any new ideas that have worked for any of you that have overcome this struggle. On the occassions I do manage to get him to attempt, he always either blows from his mouth (which I have explained he needs to keep his mouth closed to get the air out of his nose) or simply says he cannot do it.
Thank you in advance,
