There are many households where both partners need to work to provide sufficient income but if they had a baby the childcare costs would blow the budget…..so they carry being childless.
Both of my parents worked, I hardly saw my father, when I was very young, he worked away so much and such long hours. My mother returned to work just ASAP, leaving me with a latchkey. Friends and relatives, stepped in to help out. The situation has been the same, for me too - except now I am retired, there is just Avril working, and herself working long hours.
