Crying at School

Some kids dread switching to a new class or school and cry when they are dropped off for the first time. Raina has never done that (for which we're quite grateful) and she's always been happy to try her new teachers and classes. Fortunately / Unfortunately for us, she loves school so much that she cries each day when it's time to go (even though she stays a full hour later than school lets out each day). She always begs to stay just a little longer, and then gets upset when I say no.

I wonder how long her extreme affection towards school will last.
