We've had Tallulah's Tutu by Marilyn Singer for a few years and love it for many reasons. Every once in awhile we do sort through the books on her book shelves and we pass them on to others but the ballet books she tends to keep.
We love that this book has lots of real ballet words in it, we love that her little brother's name is Beckett (I have a nephew with the same name), and that there is a boy in her ballet class, and that the illustrations show a variety of ethnicity. The illustrations are done beautifully in shaded tones by Alexandra Boiger. This is a whole series; Tallulah's Solo, Tallulah's toe shoes, Tallulah's tap shoes and Tallulah's Nutcracker. If you have a budding dancer we recommend any of these titles. Tallulah isn't perfect and she learns to work at her practice of dance, learning it's not just about the tutu!
