I can only speak from my own experience... I wrote a DA letter which was ignored and I was df'd (that's what I get for being related to the PO at the time) and my child has been dropped like a rock by my JW family; that is, the family that are 'zealous'.
She has grieved losing them like a death. Now as she gets older, she realizes how dysfunctional the whole JW system is, and she wants nothing to do with it. I hope that sticks.
A few members of the family still see her (and me) but they do so in fear. It's sick. Children have nothing to do with any of this nonsense.
My JW sister (elders wife) finally cut her out completely (was her closest aunt) after I forbid her from just dropping by the house and picking up my kid and taking her out, but not seeing me! I told her I didn't know what planet she was from, but that I was not a way station for her to pick up my child and take her off to brainwas...er...instruct her in the loving ways of Jehovah. So she decided not to see the child at all.
She's missed years now that she can't ever get back...and shattered the trust a child had in her. That cannot be regained.
I pity my sister. But I know my child is better off without that influence.
