In other cases the deaths of many babies in a family seems to be a matter of the reproductive health of a woman. There is a pattern where the earliest children grow up healthy, then she starts having stillbirths or very shortlived babies - which tend to come too close together, because she isn't breastfeeding - and finally she dies in connection with the last birth. Makes me very sad to see.

It wasn't always the mother's (reproductive or otherwise) health that was the issue. What used to be known as "blue babies" (NOT the "blue baby syndrome" of today, but blood incompatibility) took the lives of numerous 2nd, 3rd, or subsequent babies. Rhesus factor incompatibility, where the mother has Rh negative blood and the father has Rh positive. The FIRST baby is usually fine. Even the second baby can be fine IF it has the mother's blood type. If baby 1 is same blood type as mum, no problem. If baby 1 has opposite blood type, no problem for baby 1, BUT a problem may be there for baby 2 if baby 2 has opposite blood type. For subsequent babies if their blood type is the same as mum's, it should be ok. It's when the baby's blood type is opposite, that the antibodies that have been building up since the first non-same blood type baby came along start to attack the new baby growing. Once we knew about blood types and what the Rh factor meant/did, we pretty much eradicated this situation, which is why the term "blue baby" now means something else.
But back in the day, many babies were stillborn, or died soon after birth because of this. It would have been even more difficult then to understand why only some babies died this way. If you had 2 babies, baby 3 died, baby 4 died, baby 5 was fine, baby 6 died .. and so on, and you didn't know it was a blood issue, you'd put it down to almost anything .. a curse, God's punishment, disease, the mother's bad habits, the mother being a fallen woman.
We have no way of knowing how many of our "died young" or "died stillborn" babies were of this, or disease (measles, smallpox, diphtheria, whooping cough), or the mother's health/nutrition, or something else.
Just something to consider. (My daughter is Rhesus negative, but was told this was not an issue for her due to modern medical knowledge. Fifty years earlier, maybe, and it could have been a different story.)
