G'day Scorpion,
You are most insightful!
This point came up in discussion amongst some Dubs in Sydney congregations a few years ago.
I believe the conclusion they came to was that the illustrations must be of resurrected children. So in answer to your question "Are these families living before the resurrection and after Armageddon?" the answer must be that they were families before Armageddon.
Cheers,
Ozzie
