We're starting a new preschool tomorrow - wish us luck

This past year we had taken our three year-old son to a co-op. Although the teacher was wonderful and we would not replace the experience with anything else, the board at the co-op was going through a very rough period resulting in the resignation of the school's director. So, we investigated other schools and found one that is 10 times better - I'm talking daily music classes and misters over the play area. Yes, misters! I tried to prep my little one today for the new school, but all he keeps talking about is his old school. I'm nervous to drop him off tomorrow - so wish me luck!
