I think that if you have the flexibility to take him to school and to his classroom your self you should definately do it. I think it's important to participate and even though it may not seem like it, by taking him all the way to his classroom you are being involved. You get to see his desk, his artwork and morning routine when they walk into class. I also have a kindergardner and I changed my work schedule to start 30 minutes later so I can drive him myself and to his classroom. I praise him for following his routine and he is thrilled that I am there with him. We were almost going to have him take the bus in the morning, but quickly changed our minds..now he only takes the bus back home.
