The Dr. Seuss Dichotomy

My mom never liked Dr. Seuss books and so I've always had a bias against them.  But now my almost-five-year-old's preschool class is studying them and I'm developing a new appreciation for at least some of them.  She came home thrilled after they read Horton Hatches the Egg, repeating "An elephant's faithful, 100 percent!" ad nauseum.  But she explained to me she didn't like the Dr. Seuss books that are "just rhyming" like Fox in Socks.  Although she didn't have the vocabulary to express it, she likes books with plot.  (This might explain why she has a general aversion to poetry but makes an exception for narrative poetry, like Emma Dilemma: Big Sister Poems.)

This school unit exposed me to a Dr. Seuss book I wasn't familiar with (to be honest, he was so prolific that I am always discovering new ones): Please Try to Remember the First of Octember!  A parent keeps promising his child outlandish things... but not until "the first of Octember."  I don't think my daughter quite got the joke that the first of Octember would never come and therefore the parent would never have to make good on his promise, but I did and it amused me!  I also like I Am Not Going to Get Up Today! although the rhyme scheme peters out at the ending, and my kids love finding all the "wacky" things in Wacky Wednesday.  As for the "just rhyming" books, I have a soft spot for There's a Wocket in My Pocket! since I used to sing it to my older daughter.  It's rollicking rhythm just lends itself to song.  And how could I not like it after she told me that I'm her "zillow" because "the zillow on my pillow always helps me fall asleep"?
