My son is 3 and he loves it! We needed more books geared towards his age. I choose this book because we were given another from the same author that he loves "Have you seen my Potty". This book is great. When they are all in bed and they hear the "rat-a-tat" at the door, my son knocks on the floor to make the sound. When they slam the door in the on the worlf my son says "Bonk". The illustrations are great. The rhyming is great because he's actually working on rhyming words at preschool. It's just a fun book for us to read each night! I highly recommend it!
