Yes I remember this when I first joined...my family, none who are in, had children and I asked what happens to the kids if the Big a starts?
I got told by an elder that the pattern in times past in the bible is that the kids were the responibility of the parents and if the parents perish the kids go to...in Noah's day, Soddom & Gomorrah etc.
So fear not, the loving Jehoover will destroy all adults AND children at the Big A...which is coming soon don't you know? I mean, it is nearly 100 years since the Great Jebus was installed as king and he has been ever so busy*...
