The Pigeon Loves Things That Go!, by Mo Willems, Hyperion Books 2005. Baby to Toddler
First a personal confession: I love, love, LOVE the pigeon in Don't Let the Pigeon Drive the Bus!. So much so that when I was decorating the baby's room in advance of the baby, I worked a little pigeon into all the paintings. Almost three years later, and I still find it amusing. So when I saw that there was a pigeon board book, of course, I just had to buy it.
And I did. Second confession: I don't LOVE this pigeon as much, but I still like it. And what's more, my toddler boy seems to prefer it to the original, at least right now. He loves the vehicles and thinks the pigeon is silly. So, considering that the Smidgeon of Pigeon series is not written for me, but is, in fact, written for toddlers, this book and the others are definitely a great investment if you are buying books for toddlers.
