My baby's going to school

We got in line at 7:40am today (we aimed for 7:30....but that's life) to sign my baby up for preschool! He's growing up way too fast. When he first came home I worried that a summer birthday boy would have difficulties in his age appropriate grade (ie barely 5 when he starts Kindergarten). That fear was quickly relieved when his smarts and social skills were evident. He's going to love preschool. Unfortunetly, we couldn't get him into the morning program, so he'll be doing afternoons 12-2 on Tu/Th starting in September. The tricky part about that is Wink's one class next semester is on Tuesday at 1:30pm. So we'll be frantically searching for a Tuesday babysitter to pick him up from school on Tuesdays. Any suggestions?
