Having children was much more dangerous in those days;one in every nine women died in childbirth.Even so,women used to have many more children than they do today:in 1800 the average American family had sevev children --today the average is less than two .Perhaps the reson for this was that so many babies died :even a hundred years ago ,20%of children died before they were five.
