My grandmother had 9 kids, the last one was born when she was 47.
He was 93 this past February. Late pregnancy are nothing new. Friends of my parents were 50 and 53 when their youngest child was born.
I wish the parents all the best.
I had a great aunt who had a set of twins at 55yo. The twins are my Mother’s age and both were normal and were concieved naturally in about 1940.
