last year's d.c. my wife's friend was getting baptized, and therefore helped with pictures in the front row.
standing next to me was mr. self-righteous elder, well his 9 year old niece was getting baptized.... he was in his full glory.
anyway many comments by elders these days, say that young baptizing is a protection for the individual.
in our non-brainwashed talk it means "get them before they think"
