What to read after Wee Willie One Sock?

The book is about a little boy, Willie, who happens to look like my son at that age. The cats are real life figures; Lucy and Matthew are the light of Jack’s mother’s life other than her son. In the book the search is on for the missing sock. They look under and by every piece of furniture in the house giving the names of the pieces to the young readers/listeners. The cats play a role in finding the missing laundry. At the end the mother’s love for her son and the cats is evident. This book wrote itself as the two authors brain stormed and laughed about the combination of ideas. Writing can be fun.
