Part of the reason parents are anxious that their children get baptized (and other jws) is that the WTS teaches that the mark for survival is baptism as a jw...otherwise children are protected under their parents mark of baptism. The problem is that the WTS does not give an age of accountability, but only hints at it. So some parents being told this want their child to have that mark just in case they are old enough to be personally accountable and especially when the WTS says the end could come tomorrow.
Look up Ezekiel 9:4-6 for the mark of survival
and
"accountability" on the WT-CD
