The WTBTS has stated countless times baptism is the most important decision/action in a person's life. Therefore, a minor, still not fully developed brain and personality must not enter into this lifetime sealed contract.
True Christians shall obey the Biblical mandate and follow Jesus' example in this and all other matters.
However, the WTBTS will not follow our Christian leader in this regard because they are interested in the numbers, as well as the psychological hold baptism puts on people.
Soooo saddened when I see or hear of anyone getting baptized while younger than 18.
