Need Help Re-Wording Poem For 1st Bday Invits

We are having a bookworm party for my son`s 1st bday. This is the poem that I found that inspired the idea, but I want to re-word it to make it more playful and to incorporate bookworm and 1st bday. Thanks for your help!

A book is a treasure
Forever & Ever

So instead of a gift
Though it’s sentiment sweet
Give Avery a book
That she will keep and keep

Please sign your name
As your personal touch
And Avery thanks you
Very much!
