The Sandra Boynton series is refreshing and fun. The rhymes are silly but often have thoughtful underlying messages. Some favourites in our family: But Not the Hippopotamus, Night Night Little Pookie and Moo, Baa, La La La! Available at most book stores, kids usually get the most out of them from ages one to about three. (Indigo, price for one $7.99 or Boynton's Greatest Hits - includes four books - $17.81)
