Speaking as a 54 year old on the Autism Spectrum who also suffers from Sensory Integration Disorder, this little guy has a lot of red flags for both. (They very commonly come as a package deal.)
I'd get him evaluated by both a neuropsychologist and an Occupational Therapist (OT) as soon as possible.
The sooner interventions are put in place, the better his chances of living a happy and productive life.
Congratulations on seeking help so early. You're a good mom!
