Reflecting the child's attempt to impose logic on a world he is just beginning to observe, this asks some very ""sensible"" questions. If ""frogs have tadpoles and horses have foals"", if ""ducks have ducklings, does bread have rolls""? If ""goats have kids and pigs have shoats"", if ""sheep have lambs, do ships have boats""? The answers are as directly advanced as the questions and the one basic concept that disrupts this innocent system of logic is clearly explained. ""For things can't have babies, whatever else they do, only animals and people, as your mother and father have you"". With the help of Marjorie Auerbach's rollicking pictures and these simple little rhymes, pre-schoolers are invited to ponder a brand new idea and observe its proof wherever they go.
