We love the old school Sesame Street. So when Kieran saw The Ernie and Bert Book by Joe Mathieu at his grandparents' house, he wanted to read it. I'd forgotten about the book, even though I'm sure I'd read it before. The story involves a long, convoluted explanation from Ernie as to why Bert needs to wear a pot on his head instead of his cowboy hat. It's a great story with these classic, lovable characters. I think any child who likes Sesame Street will also like this book (and as a bonus, the parents will also have fun reading it to them).
