Although I encourage parents to start telling children about donor conception when they are under five. I know that there are many families with older children sometimes even adults themselves who we have not ‘told’ yet. Telling children about their origins by donor conception puts honesty at the heart of family relationships. Is respectful of donor conceived children/people as individuals in their own right. Allows donor conceived people to make choices about their lives. Allows donor conceived children to learn about aspects of their history. Integrate the knowledge as they grow up and accept their story without shock or distress. Means that significant differences between a child and parent in looks, talents etc. can be easily explained. Some DC adults have thought they must be adopted or the result of an affair by their mother. Does not mean that children will reject their non-genetic parent.
