3. Extreme Lack of Sensitivity
Sometimes autism may lead to hyposensitivity instead of hypersensitivity. In this scenario, children may not respond with the kind of instinctive reaction on exposure to stimuli as you would expect. They may often put themselves in dangerous situations being visibly unperturbed by the consequences. If you find your kid burning himself in the shower, being nonchalant in the cold, feeling nothing on insect bites, etc., you should take it as a warning sign.
