During the late 1970s I saw that a young sister my age got engaged to be married. I thought that was bad because of the Bible verse that said "woe to any woman who has a suckling child". That was the mentality back then.
There is also Joseph's Rutherford's book Children, written in the 1940s, where the characters John and Eunice forego marriage and having children because Armageddon was close.
