What I am putting in this post is based on my life and may or may not work for you. I hope some of it helps somebody.
Never talk bad about your witness spouse.
Let your kids know you love them no matter what. Witness or non-witness doesn't matter. That sounds easy but in reality it can be tough when they get older and are still becoming little witnesses. But, if you start early and reconfirm this message it will sink in. I've found that you have to hit this message in two ways. First, by action. They have to see in your actions that you love them even when they choose to do something witnessy. Second, by words. Don't just rely on them to see your actions and understand their meaning. You must reassure them verbally that you love them no matter what. Discuss it with them and tell them you will love them no matter what. I don't think you need to specifically mention the witnesses but kids sometimes will ask questions like "if I ruined our car would you love me?!?'. Answer yes and elaborate as necessary.
Ask your kids if they believe God loves them. Also ask them if they believe God loves yourself and/or your spouse. Talk about how God loves everyone and how Jesus died so everyone could have life. I think the object is to stress everyone versus specific ones. Ask them what people need to do to live forever (I never added on earth or in heaven) then Read Acts 16:23-35 or summarize depending on their age. After you've read it a few times spread apart by a week(s) or month(s) you can keep hitting the mantra of "what do we need to do to live forever?" This seemed pretty powerful without even talking bad about the truth. Hit the subject of Grace along with this. Grace is never discussed at the hall and when it is it's called undeserved kindness. They won't fully understand that they are the same thing. I can't stress enough that Grace is a doctrine that IMHO gives kids a sort of inner calmness. Plus they'll wonder why such a cool thing isn't discussed at the KH.
I totally agree with teaching them to think and see through the BS of life. Others have covered that very well.
I have also found that witness parents tend to be busier (in a made up stressed out sort of witnessy way) than the non-witness mate. Take advantage of all the time you can to spend with your kids. If your kids go to the meetings regularly but then are sick one night - be there with them to take advantage of that time. If the spouse goes in service and you and the kids don't - be there with them and maybe even take them to breakfast.
Encourage non-witness friends and after school clubs. Kids are naturally drawn to both these things so its fairly simply to naturally let it happen. Perhaps your county or city has recreation facilities with kids nights or various classes. Some of these can be done as a family. The idea is to have fun with them and to let them have fun with others their own age away from the indoctrination. When they play with other witness kids they tend to start using the same words and terms and that's a slippery slope.
Use standard Christian terminology if you are a Christian. Use the word cross. Say Bless you after a sneeze, have fun clinking your glasses at dinner (even if it's just ice water), tell them to have a blessed day when leaving for school, remind them that Jesus if our king, redeemer, judge and intermediary. When appropriate ask them what Jesus would do. I find that making Jesus the focal point highlights the fact that he isn't talked about in that way at the hall.
Just my thoughts.
