Today's episode comes to us as a result of a listener who wrote to me saying she and her partner don't want another child but are worried about the potential impact on their daughter of growing up without siblings.
Personally I don't have this problem; my own selfishness about not wanting a second child has overridden the issue of growing up without siblings to the extent that I had actually never considered it a potential problem until I received the question. But having pondered it and found that there is some research on it, I decided the time was ripe to find out whether only children really are as awful as popular wisdom says they are.
Listen up, my friends. Will I be vindicated, or will I throw away that pack of birth control pills before the end of the episode?
