With JWs, you'll soon realize there is no "free exchange of ideas". They have the attitude that "they're correct, and everybody else is wrong!", and that's all there is to it.
The only thing I have to tell you is that you being the head of your household, according to their own teachings, you have a heck of a lot of power in your hands. Play your cards right.
With a JW in the house, your kids will be indoctrinated. No questions asked. The JW in the house will find a way. Soon the non-JW is viewed as the bad guy, the guy that will soon be destroyed in Armageddon.
I'd get the children exposed to as much extra curricular activity as possible, as well as in their school work, so that their time is well occupied. Otherwise that same time will get occupied with WTBTS stuff and you'll be doomed.
Like if you get them involved in some sort of sport, or instrument playing, etc., that activity can take up the time dedicated to the JW meetings.
It's a complicated game now with a JW at home. Play it right, for the sake of your children.
