It doesn't take modern science to figure out the advantages of spacing births: the !Kung people (modern African hunter-gatherers) figured this one out a long time ago. Wet-nursing is also not a modern invention, and when calories are scarce, breast-feeding is a stronger inhibitor of fertility than it is for well-fed moderns.
