Moo by David Larochelle. When you read a book the MOMS love, the babies listen up too! Larochelle tells the whole tale of an adventurous cow stealing a car with an inevitable disaster, using only the word MOO. You supply the drama.
Rosie's Walk by Pat Hutchins. A Big Book is ALWAYS a hit -- everyone can see the pictures. This is nice too because it's all prepositions -- you can use those motions. This year I added as I read, "But where is the fox?" after each bit of text about the chicken.
Old MacDonald Had a Farm. I pulled the critters out of the bag as I turned the pages of the pop-up book in Office.
Clip-Clop by Nicola Smee. In Room on the Broom style, Mr. Horse gives all the farm animals a ride, (Clip-Clop, Clip-Clop) until Plop! Plop! Ploppity-plop! Stan taught me how to do the clip-clop sound by sort of squinching your jaws together into a vacuum and then applying pressure with your tongue. A very impressive sound and easy to speed up as the horse goes faster. Really pulled the kids in.
Wheels on the Bus, with a lot of farm animals boarding.
Barnyard Dance by Sandra Boynton. This book has such great rhythm. I love to dance to it.
