As an avid reader myself, I have always really enjoyed reading to my kids. For my son, who is now five, we've run the gamut from board books to picture books to Dr. Seuss, and now he's in a phase where he is interested in and asking questions about lots of things. Why is the sky blue? Why is the grass green? How do fish breathe underwater? THERE ARE SO MANY QUESTIONS.
What are your favorite books for this age group?
