Someone had told her once that mothers existed to blunt the existential loneliness of being a person. If that was true then her biggest maternal responsibility was simply companionship. You bring a child into this fractious, chaotic world out of the heat of your womb, and then spend the next ten years walking beside them while they figure out how to be a person. Fathers, on the other hand, were there to toughen children up, to say Walk it off when mothers would hold them if they fell. Mothers were the carrot. Fathers were the stick.
