Before the first day of school, there is always a little apprehension. Even with a new Spongebob backpack and R2D2 lunchbox that makes sounds. We were impressed that he didn't seem very nervous.
After school:
Yay!! He had an "awesome" day!
When I picked him up and asked how his first day was he asked, "Today was my first day?"
He felt so comfortable at his new bigger school that it seemed he had been there longer than one day! (same school, new campus).
Five of his friends transferred also. They played tag on recess. A few new friends played, too.
He said, "I like school! It's super duper fun! Sort of."
I like that he put a qualifier on the end, just in case it changes.
