Praised for acting like a big girl when she is small, as a young girl grows, "big" becomes a word of criticism, until the girl realizes that she is fine just the way she is.

Gertie is the littlest yak, feeling stuck in her smallness--she wants to grow UP and have bigness and tallness. But when it turns out that there are some things that only Gertie can do, might she come to see that she's perfect, just the way she is? A rollicking, rhyming, heartwarming and reassuring story from debut author, Lu Fraser and much-loved illustrator, Kate Hindley.
