Summer camp recommendations for 3yr olds?

My childcare syncs with Knox county schools so they close for the summer. I work from home so last year I tried to make it work with my son (3m) home with me, but it was a struggle. This year I really want to put him in some kind of childcare while school is out for the summer until his preschool starts again in the fall. The programs I’ve found so far are mostly for 5yrs+. Any suggestions or recommendations for a summer program for a 3yr old?
