But the fundamental idea was that the German people would pop out enough babies to eventually replace fill up any lost factory jobs as well as provide the numbers to properly work the conquered lands and fill them up with a robust German population and . . . Well . . . I think you get the idea.
As I believe I said earlier in the thread, they hoped to have a population of 300 Million by the year 2000. Something the United States was unable to achieve, and it already had a larger population than Germany in WW2. (That being said, they could still come pretty close to hitting 300 Million by the year 2000. At minimum, I'd expect 250 million Germans by then.)
I'll quote AANW again
Women who had LESS than six natural children were seen as "failing to do their part for the Fatherland". Those who had eight or more received stipends from the state (which increased as family size increased). That many women physically can not manage that many births was totally ignored. Women with NO children were treated almost as non Aryans.
The entirely male leadership of the Reich literally did not believe reports from medical professionals, even major research centers, that these policies were resulting in increased deaths, both of infants and of mothers.
Of course. The reality, however, is that some women can not medically handle being "barefoot and pregnant", which is what having 6 or more pregnancies amounts to (that is real "stair step" kids) regardless of the medical help possible in the 1940s. Some women have no medical issues with even double digit successful pregnancies, most, however, will run into difficulties at some point.
There were some attempts by individual doctors to put their thumbs on the scales one way or another. That rarely turned out well for the doctor involved.
