Baby einstein's; Let's Explore Poetry is a great little book of poetry for kids. I recommend this book to read to your little ones. Here is one cute poem from the book.

Animal Crackers by Christopher Morley
Animal crackers, and cocoa to drink,
That is the finest of suppers, I think.
When I'm grown up and can have what I please,
I think I shall always insist upon these.

What do you choose when you're offered a treat?
When Mother says, "What would you like best to eat?"
Is it waffles and syrup, or cinnamon toast?
It's cocoa and animals that I love the most!

The kitchen's the coziest place that I know:
The kettle is singing, the stove is aglow,
And there in the twilight, how jolly to see
The cocoa and animals waiting for me.
