If you are a lesbian couple who had kids using a known donor...

How old were your kids when you started explaining to them about their biological father? Our son is almost 3 and knows/has a relationship with his biological father (he is known as uncle so and so). He's also becoming aware of family dynamics (two moms, a mom and dad, etc.). How did you handle this and how did it go?

We didn't use a known donor, but we did use this book to open the conversation on family structure:

It's awesome.

Here's the description:
Geared to readers from preschool to age eight, What Makes a Baby is a book for every kind of family and every kind of kid. It is a twenty-first century children’s picture book about conception, gestation, and birth, which reflects the reality of our modern time by being inclusive of all kinds of kids, adults, and families, regardless of how many people were involved, their orientation, gender and other identity, or family composition. Just as important, the story doesn’t gender people or body parts, so most parents and families will find that it leaves room for them to educate their child without having to erase their own experience.
