My five-year-old, pondering the egg smeared on his English muffin the other day, said, "Mommy! I bet Mo Willems is writing another Elephant and Piggie book right now!" 
 This kid is a fan of all things Mo Willems. He loves the Pigeon and Leonardo, and he respects Knuffle Bunny as part of Willems' oeuvre, but his favorite books are the ones about Gerald and Piggie. This is perhaps because they have such relevance to our daily lives. 
 What should he wear to his friend's birthday party? Gerald and Piggie know! 
 What should we bring when we go for a drive? Ask Gerald and Piggie! 
 I find the lessons pertinent even to my grown-up life, like the other day when I whipped up a frozen banana in the VitaMix and wondered, "Should I share my ice cream?" (I ended up sharing it.) 
 And now that we've read all of the Elephant and Piggie books published so far, we're finding out firsthand that Waiting [for the next book] is Not Easy!
