I cried the day I took my son's registration packet to school. I'd like to tell you that the first day was the hardest, but for me the first 3-4 weeks were equally as hard. I had so many concerns.......... "Will he find his classroomm okay?" "Will he wander outside unnoticed to look for me?" "Will he get on the correct bus to come home?" "Will the bus driver allow him to get off at the wrong bus stop?" haha I can tell you now that my son amazed me. He took to kindergarten like a pro and has grown so much since September. The teachers and principal really do work hard to keep every child safe and where they should be. (I'd like to think that it helped that I also taped a big yellow piece of paper to his backpack with his teachers name and bus number on it so that in thee event that he did wander the wrong way the teachers could read the note 15 feet away. haha) One way I helped my anxiety was to volunteer in his classroom once a week. I wanted to see for myself that he was adjusting and doing okay without me there. It's bittersweet, it really is.
