Query: BEST PreK-Grade2 book series EVER!!!

It was love at first sight. After finding Mo Willems' "Don't Let the Pigeon Ride the Bus," my son was hooked. He couldn't wait to read it by himself.The name Mo Willems doesn't ring a bell? He is a 6 time emmy award winner for his work as a scriptwriter and filmmaker at PBS' Sesame Street. And he head-wrote the first four seasons of Codename: Kids Next Door."Don't Let the Pigeon Stay Up Late" lovingly teaches children to laugh at themselves and to be good role models. I highly recommend purchasing the whole series. We can't wait for the next book!
