Query: The best children's book ever

I just read the other reviews of this book and feel compelled to add that it had a similarly profound effect on my life. It is only published every 20 years--1947, 1967, 1987 and hopefully again in 2007. It is the best children's book ever--an unrivalled compilation of timeless--and non-commercial--poems and rhymes. Only Shel Silverstein has come close to achieving the same greatness. I learned the whole book by heart as a child and my grown up sisters and I still recite the rounds together when we are feeling silly. Everyone should have this book in their permanent collection.
