My son has recently been recommended for therapy with an Occupational Therapist for Sensory Processing issues. While researching what all that meant, the term Asperger's kept popping up everywhere. After reading a lot about Asperger's I'm actually considering the possibility of whether or not he could have that. I read that early detection is best. Should he be tested during Occupational Therapy? And when is it too early to consider this possibility?
