Baby Shower Verbiage Baby Shower Question?

Baby Shower Question? - baby shower verbiage

I throw my sister a baby shower in August and I like the idea that all are willing to bring a book to the library to start children. The shower is family and close friends, so even if some books can be expensive, I know from my family, not be rude to be happy. What I need is an idea for a poem or tirade put that in the invitation, an idea?
