“Green Eggs and Ham” by Dr. Seuss (Theodore Geisel)
This is one of my favorite Dr. Seuss books. It has the advantage of making sense (trust me, not all of them do). The rhythm is wonderful; it’s fun to read and listen to. Plus, you’re going to want to practice your Dr. Seuss tongue twisters for later.
“Llama Llama Red Pajama” by Anna Dewdney
The rhythm and rhymes in Anna Dewdney’s books are so satisfying that I could read them again and again, even to my navel! Which is good, because that’s what you’ll be doing with a baby in utero. This title is a must-have when your child is older, so you might as well get it in rotation now.
