I've read this whole thread and am glad to see that a few have addressed what a problem the Watchtower poses for children. Please, for the love of all that is holy, exert your headship rights and forbid your child to attend the meetings or go out on field service! This cult and its literature will fill his head with frightening images of Armageddon, pound it into his head that higher education is on par with drugs and alcohol, threaten him that God disapproves of masturbation, threaten that he, his "worldy" friends, father, and relatives will be killed, and make his life at school a living hell by forbidding the flag salute, singing of the national anthem, celebrating all holidays, and participating in clubs and sports. Also let's not forget the Watchtower's MASSIVE problem with child molesters. I'm not saying that most jws are child molesters, but the few who are child molesters aren't made known to the congregation. Watchtower doctrine requires two witnesses to sin, even in the case of child molestation. Even if the molester confesses, his or her presence in the congregation is not announced if the elders judge them to be repentant. There are many news accounts where elders have threateningly encouraged parents of raped children against going to the police. Read the following links for more information:

There are also several newspaper and news broadcasts discussing this problem. Google it or check on Youtube. Look, the mindset of these people is truly dangerous to any vulnerable person such as a child. As a victim of both child molestation and domestic violence while under Watchtower control, I can honestly tell you that there is some mighty twisted thinking going on in this organization. Keep your kid out of it at all costs. If the Watchtower destroys your marriage as it has many others, pursue your child's protection from this vile corporation to the fullest extent of the law.
I'm sorry to sound so melodramatic, but I've lived the nightmare, my friend. I'm coming up on 24 years of being out of the organization, yet I'm still conversing with exiting and ex-jws everyday. Why? Because the only thing in my life that keeps me up at night is KNOWING WITHOUT A DOUBT that molestation of children and violence against women is being covered up by this destestable, filthy cult.
It's good your wife doesn't want your son at the meetings. Keep it that way! And as head of the household, do not allow her to make any decisions about your son's education or medical care. And never allow a jw unfettered access to your child...period.
Edited to add: If your child attends meetings and field service with his mother, he will be encouraged to teach and pursue baptism just as is being done to her. The difference is that she's an adult. But young children are highly encouraged to get baptized as well. Then if they do something against the Watchtower doctrine, expess disbelief of Watchtower doctrine, or simply stop being a jw, he will be shunned by most if not all of his jw associates, including his mother, whether or not he is disfellowshipped.
