This book was a hit with my 4 year old. I have also read this book to a group of about 10 kids between the ages of 2 and 6 and it also worked there as well. The book is repetitive, which is great with kids. After a a few pages they will catch on to the pattern and begin singing along or shouting the number of remaining buttons. Tons of fun!
The art is cute, the fonts are fun. I also love that Pete is a gnarly carefree American cat dude who skateboards and surfs.
I got this book before I knew who Pete the Cat was, and I was also unaware that there is apparently an entire line of Pete the Cat products available. I haven't tried any of the other Pete the Cat books or products, just this one.
