Sounds like you are on top of things.
Just a word of warning, though.
From time to time, the Watchtower publishes articles that change overnight how JWs look at things and behave.
For example, if they come out with an article saying that JWs whose children aren't believers have an obligation to aggressively witness to their grandchildren, your parents could be expected to change immediately.
It wouldn't even have to be that specific.
If the WT starts saying that Armageddon is so close that JWs need to abandon any passive "win them without a word" strategies, that would likely trigger an immediate change as well.
Your awareness of the dangers is a big plus for your kids.
Stay vigilant.
