One spring, as part of their animal rescue work on Hazel Ridge Farm, Gijsbert (Nick) and Robbyn van Frankenhuyzen find themselves caring for a lamb and an orphaned fawn at the same time. They name the lamb Teeny Weeny and the fawn Itsy Bitsy. Raised as "siblings", the two youngsters are inseparable that summer, sharing a playpen in the house, romping together, and just getting into general mischief. As the seasons change, Itsy Bitsy and Teeny Weeny grow into their true selves, away from "Mother" Robbyn and each other. Nature must take its course and the two animals go their separate ways: one back to a life in the wild and the other on to domestic farm life.
