The Pea That Was Me Volume 3: An Embryo Donation Story is great way to introduce children conceived through embryo donation to the idea that "some very nice people" (a man and a woman) donated an extra "pea" (or embryo) to help bring them into the loving arms of "mommy and daddy". May be read to children as young as 3 years old, and has room at the end to fill in your own child's details. Appropriate for both anonymous and known embryo donation as an initial introduction to the concept.
