General Discussion

Two of mom's neighbors (she grew up in a working class/immigrant Los Angeles neighborhood a couple miles away from the oil fields) had newborn babies die of a bleeding sickness.

The mother living next door to her had delivered seven live birth babies but only four survived the first six months. Those kids grew up fine and healthy, but still.
Three babies that everyone in the neighborhood knew within the first couple days were failing to thrive, and would die.
Mom still remembers how that affected everyone, including neighbor families.
The delicate social dance of playing or visiting at playmate homes that had been set up to welcome a new baby sibling, but were now being reset in anticipation of a funeral.
The anxiety of all the parents in the neighborhood. A feeling of holding one's breath, considering one's words, waiting for the inevitable.

And this was in the early-mid 1940's. And neighbors were more likely to look after each other in these situations, even if there were conflict between families.
