This book is pure joy. I loved it when I was young. I picked it out for my daughter because it brought back the fondest memories of my own childhood. By the time they are two, children can easily memorize it and begin to distinguish words on the page. It's now become my daughter's favorite book to read. We both know it by heart. This is a must-have in any children's book collection. I highly recommend it. Another great book series for kids is "Why some cats are rascals".
