At the "Children of the KIng" St. Louis convention in 1941, over 1300 children were baptized. Some were as young as six years of age.
The book "Children" was released at that same convention.
(Sam Herd was born in 1935.)
The current child recruitment push is reminiscent of the 1941 child recruitment. Interestingly enough, the Tower was embroiled in lots of court cases then, too. The children in 1941 were being indoctrinated into making a pledge of allegiance to the Society in order to challenge the American pledge of allegiance.
The WTS recruited children back in 1941 to challenge the American courts. It worked back then and I suspect that the WTS is doing the same thing now. There will be an underlying purpose that has nothing at all to do with the child's salvation.
I think that the WTS push for child baptism is a calculated move and that the purpose will be revealed in court cases yet to come.
