Think it is just a sign of the times Susie. People getting married later, combined with average divorce age in early 40's and they wish to have another child with a new partner.
Is slightly on the edge of a little too old ... but not quite if they are energetic and healthy, and have a supportive partner. Health care, of course, is better now and a good chance of mother and baby getting through it safely, unlike many years ago. Always surprises me when you start looking through the censors of late 1800's, etc., lots of children born to women of this age group .. course no birth control then.
Best of luck I say.
