Thanks for the toilet info! I assumed a “pit toilet” was just a deep hole in the ground and, once it reached a particular level, it would be capped and a new hole would be pressed into service. But yes, if it was pumped a baby would definitely clog up the works!
The out house pit toilet is only legal for individual camp sites
A campground pit toilet will most likely be a concrete pit like a dairy farm has for the collection of manure.
By the way, when you look down into those pits, it is never pleasant.
But if I looked down and saw a dead baby, it would be the worst day ever.
Grandma/great aunt must be a very special person.
