I do recall a young couple asking us about having children in "The Last Days". We already had our kids so to late to say know, but we referred them to a couple that we know made the decision to "wait until after Armageddon". This couple was now in the late 50s and we even were not sure if they had regrets.
A couple of months later, our young friends announced that they were expecting their first child.
I'm guessing they got some good advice from the older JW couple.
