My husband believes we stopped at one child because we mutually decided our family felt complete. I encouraged that explanation.
The truth is childbirth frightened me far more than I ever admitted. I couldn't face doing it again, but I felt guilty saying that because my first delivery was considered medically "normal." So I turned fear into a practical discussion about money, space, and careers. He agreed. I still wonder whether he would have wanted another child if I had been completely honest.
