You're welcome, John.
Stan, I guess it depends what sector of people you're looking at because for the richer folk, as medical technology improved through the 1800's - which it certainly did - they could afford and were willing to use it. For the poorer folk, however, and I refer here specifically to areas like the East End of London, child mortality was very high. I don't have exact stats off the top of my head but there are some shocking stories of the lives of infants in Victorian London.....those who were lucky enough to make it past the age of 5 would mostly be put to labour soon afterwards anyway.
Cheers,
Adam.
