L.M.
My kids go to Cornerstone. It's not half day, it is 8:30 to 4:00, on Tuesday/Thursday. You get to have two entire days to yourself while your son is having fun, learning and being very well taken care of! They have a curriculum with singing, letters, numbers, bible story and craft. The teachers are sooo nice and love the kids! My daughter is 2 and already knows her ABCs!! And Cornerstone is inexpensive--for both of my kids I pay $260/month!!! Good luck!
