Dear Amy: My spouse and I have decided not to have children. This is for several reasons, including: (1) we have multiple pets whose companionship brings us immeasurable joy, and are quite happy when we are together with just us and our pets; (2) we are both busy working professionals with established careers who travel a lot for work and don’t see each other as much as we would like to as it is; and (3) health and financial reasons. My spouse has a brother and a sister, each of whom is married with their own young children.
