@rotatingskull right, but breastfeeding is so very integral to the raising of children that it would make sense, at least to me, that both parents would be able to feed their offspring. That way if one of them died, the other could still raise the child to maturity. But I guess this is less about humans than whatever the world was like for very early mammals.
