In reply to your 2/05 post last baby ever born? (fivedoves.com) in my opinion the last baby to be born will be during Jesus' 1,000 year reign on Earth.  After the great white throne judgement, the population should be a fixed number.

I have often thought that the sheep & goat judgment of Matthew 25 takes place at the very beginning of the millenium when Jesus reigns for 1,000 years on Earth.  In that case, the people left on Earth after the Antichrist's reign would either go into everlasting life as the sheep or be sent into the lake of fire as the goats so who would be left to populate and bring children into the world during the 1,000 years.  So the sheep & goat judgment must take place at the end of Jesus' 1,000 year reign on Earth so that Isaiah 65:20 can take place.

Isaiah 65:20, "There shall be no more thence an infant of days, nor an old man that hath not filled his days: for the child shall die an hundred years old; but the sinner being an hundred years old shall be accursed."
