Agree with the first two posts, books that emphasize the fun but important parts of school especially kindergarten are so great for kids and having him pick out school supplies. How about also including a couple of trips to the new classroom before the first day jitters. Having him see his classroom now and then transformed on the first day by his teacher could be a wondeful stepping stone to encourage his new adventure. Plus he could feel really important meeting and spending some one on one quality time with his new teacher. I am sure in a matter of the first week or two he will love his new found classroom and the adventures in store. Good luck.
