Preschool in one week!!

AHHH! I'm nervous :/ My son starts preschool in a week. It's one of those things that your child accomplishes as a milestone and it's so bittersweet. I want him to go to school. I know it will help him. But, my baby is growing up too fast :( Same thing is happening to his baby sister... she'll be one in a month and a half! He will be turning 3 this coming Wednesday. It's too much at once! Birthdays and first days at preschool!! Oh, and his first dentist appointment on the 23rd. It's all one big ball of craziness. Maybe this is why I've been having trouble going to sleep. All these big things coming up all at once. My brother is also going to be getting married, maybe this spring. It will either be Ohio or Tennessee. All I know is this... two children, 1,500 miles, autism... yeah. A trip on AMTRAK or however you spell it will be the way we go. There is no way on God's green earth that my son will sit still on a plane for longer than half an hour without screaming. The passengers will start complaining then we will be diverted to some city somewhere and be escorted off the plane. You'd see the story on CNN or something. Um, yeah, no thanks. Craziness... pure craziness.
