Query: My son's favorite book.

My son has loved this book since he was an infant! He is now 2 1/2 years old and we still check it out of our library regularly. Before he was one he was able to identify the beautiful characters and objects in this book. As a side note, after reading it about the first twenty times or so, I realized it fits perfectly into the rhythm of Donovan's song "Yellow is the Color of My True Love's Hair." Now more often than not, I sing this book to him! If you are familiar with the song, try singing the book to your child. It's so great!
