So, in honor of Luca's sixth birthday, here is an A.A. Milne poem I have been waiting to use literally for years.
When I was one, I had just begun.
When I was two, I was nearly new.
When I was three, I was hardly me.
When I was four, I was not much more.
When I was five, I was just alive.
But now I am six, and I'm clever as clever,
I hope I stay six now,
Forever and Ever.
