Very involved. Everyone at the school knows my first name and I know theirs. It was quite shocking last year to find out that one of the new teachers knew exactly who I was and who my children were before the end of the first week of school. She didn't have either of my boys in her classroom either.
I do as much as I can. My oldest is going in to 2nd grade and I have always been a room parent for his classrooms. I am also PTO VP. I wish I could go in and volunteer more during the day, but with 2 smaller kids, I can't get in as much.
