Also, is your son involved in any sort of organized actiity, anything from Sunday school to sports to music? Has your son previously been in daycare that may have already provided him the sorts of experiences that preschool offers? To me, since academics aren't a concern at all, preschool is just about the child learning to separate from you, learning to listen to another authority figure, and learning to problem solve with other kids.
Maybe this would help your ds not feel so lonely? Any activities like this in your area?
Are you available during the day? Maybe you could host/sponsor a recurring activity.
Before I went back to to work full time I joined 3 other families and created a co-op. My ds went from 18 to 24 months and it was really great for him.
