The way Village Sim works is that the villager who initiates an activity is the one who improves in that skill, whether it is farming, building, healing, researching or breeding. If your lifelong mom didn't initiate most of the encounters that produced her children, then her skill as a breeder would remain low. That situation is not a reflection of any view of parenthood, but rather a practical programming model that has been used throughout the game. I always have the ladies in my games initiate the romantic activity, because that strategy gives me better control of population growth, and I don't have some rogue male spoiling my plans by sending my highly trained females to Village Center for 2 years at a time!
