The following quote if from the book Children published in 1941 by the Watchtower.
"No children were taken on Noah's ark or were born on the ark...this would show it to be proper to wait until after Armegedon to bring children into this world...it is only a few years from the time the other sheep are gathered to the Lord, until Armagedon...those who have infants during Armagedon will have much greater woe...it would be a far greater difficulty to care for them during the great tribulation..." Children book 1941 p.281
Many of the JWs who took to heart these statements are now dead.
