Scheduling Dilemma

I am not a fan of shoe-horning activities into a child's day. That said, James is getting the last of several services this month. Preschool for special needs kids. SHAPE assistant hours (with constraints but also with a fabulous woman).

M-Tu-F, James has a decent schedule, with only preschool in the morning. W-Th, he has program for most of the day, with a 2-hour gap of doom in the middle. In theory, he can rest in that interval. What it actually does is push him. Sometimes that's good. But other times, he gets pushed over the edge and:

He gets sick. We had carsickness last Friday, followed by a summer cold, which he gladly shared with me.

It's so scarily easily to just sit and do nothing. That's not good for James' growth with speech and development in general. I am constantly striving to balance. A formula for success has so far eluded me.
