Gracie's first day of school

Well it has come! The IEP is done, the bags are packed, and tomorrow Grace goes to her first day of school. My baby, my little 2 (yes maybe almost 3!) year old baby has to get on a bus ALONE without me, and ride to school, get off the bus, then spend 2 1/2 hours at school then ride the bus home without me again! Needless to say, while I am excited about the oppurtunity and what it is going to do for her (and me!) can I just say mommy is having a HARD time with this! What ways did you cope with your kids going to school?
