Yes.
Focus not on the problem, but on the policy which protects the org rather than the children. Don't be too harsh. Just tell the truth.
Discuss blood. That is madness.
Explain disfellowshipping. How if you publicly disagree with the governing body about any "current" doctrine even though it is subject to change, that you can be disfellowshipped, which then makes it a disfellowshipping offence for any current JW to speak to you. It is just too much control.
If you celebrated your birthday, or the birthday of your child, that would be a disfellowshipping offence.
Then if doctrine turns them on, you can bring up the changes in doctrine over who is chosen by God, who the GB are, and what kind of power they weild and then enforce through DF'ing.
Make sure you explain you have no beef with JW's. They are good people trying their best, but that the leadership has exerted much too much control over them. Give her a few things to bring up in her study, and then tell her to pay close attention to the reaction of the person studying. Do they say it is all lies without even investigating? Are they willing to investigate? Did the word apostate come up?
Since you can most likely predict the reaction and weirdness of the study condustor, that is your ace in the hole I think.
