What a marvelous update to an old sing something rhyme. The old rhyme was what are little boys made of snakes and snails and puppy dog tails, and just all these things that we considered so vehemently boy. This book says boys are made of everything and can be anything. They can be happy. They can be sad. They can be in touch with their feelings. They’re helpful. They’re kind. You name it boys can be it.  It works quite well, and illustrations are lovely.
