My four-year-old preschool students tend to like Gerald's books (this is the third one of his books that I have downloaded). I was pretty confident that they would enjoy this one. We weren't dissapointed.
I love his use of rhymes. While the rhythm gets off on some of the rhymes, it generally flows well.
This tells the story of a group of people who have old hats, but they don't worry because a "Happy Hatster" will come and give them a hat for happy hat day. It's good, clean, and very silly fun. My daughter (age 3) laughed at the picture of birds building nests in the old hats.
I would have given it five stars had it not been for the funky rhythm towards the end.
