This book is both of my girls' favorite. They are aged 8 months and 2 1/2. Everynight we read 2 books. It's always this book and one more. My oldest says the animal sounds and helps me read it. She LOVES it so much. Calls it her cow book. If we don't read it she gets very upset! I love the story. The very end of the book where it says "It's quiet now what do you say?" My daughter always says "I love you!" and it's the perfect ending and perfect for right before bed. :) I love it. I have since bought more Sandra Boynton (sp?) and I love all of her books but this is definitely a favorite!
