Conditions: Autism , high mobility , non verbal , learning difficulties
Conditioning with white noise at night may help. Apps are available that produce white noise, for the iPhone or android.
Cotton balls coated with Vaseline may be more comfortable than earplugs even if not as effective in reducing noise exposure. They may however be better tolerated than traditional earplugs.
Finally, auditory integration training is a somewhat controversial mode of therapy for this problem, but you may want to search for a provider in your area, and discuss the situation with them.
I wish you well.
