These nursing mothers, If one does nothing but wander around caring for baby, then she should not get any more points that what is already awarded for parenting.

However, If a nursing mom, teaches the other children, tells them stories, makes stews (on her own without being dumped in the stewpot first), collects and does ALL the villagers laundry, wanders the village collecting things for the scientists or food bin..........then she should gain more points in some kind of skill...(parenting if she doing domestic stuff....farming or research...if she collecting.) If she carried that baby on her back.......which villagers would....it would leave her hands free to WORK and earn her skills.
