Where the Sidewalk Ends
If you have not read Where the Sidewalk Ends, or have not read it in a long time, I highly recommend you do. Shel Silverstein is in possession of a unique brilliance and this title, in particular, is evidence of that. It is a literary treasure. Read it aloud cover to cover.
I have a few Silverstein books that I read to my daughter at night. This is my unquestioned favorite. It is a bit dark and long winded in some places for a three-year-old, but she definitely enjoys it.
When you have finished that I advise you to look up the musical credits for Silverstein.
