I have never been an elder and I think you cannot help others to wake up (especially without risking a lot in your position), but you could delay their baptism so that to have at least the opportunity to be awaken at that age.
As a PIMO parent, with a PIMI mate, this is what I biblically think, and it is nothing that you could label as "apostate" and as a PIMO elder you could do something similar as well.
My child (and children in general) should get baptized only:
1) When it he will be 30 years old (or, at least 18). Jesus set the example in prayers etc., so he set the example also for baptism: not before he was 30. He was perfect, he was the God's son, and he knew the salvation of all humankind depended on him, so he was the best example of a person who should have been baptized as soon as possible with a sense of urgency and he did not do before he was 30.
In the NT accounts you can always read about men and women getting baptized, but never boys, girls, or kids...
You could say that a 11, 12, 13, 14, 15, 16... years old person is a man or a woman, but when you are at that age you are not mature enough to choose a mate for all your life: how could you be mature enough to choose the real God and His religion forever?
They could say: but the end is very close! Yes, but if it should come tomorrow, it would still be plenty of 10, 9, 8, 7, 6, 5, 4, 3, 2, 1... years old JW's children not baptized: why not baptizing them as well, then?
2) After reading the entire Bible at least once. If studying one or two books that teaches you a few hundred of verses without context is sufficient to get baptized, why did God write thousands of verses in the Bible? Just for having something to read as a hobby only after the baptism?
3) After knowing that secrets books exist containing hidden information regarding the way you will be judged. If having secret/hidden books/information is God's will, why not telling this to people before their baptism instead of discovering it only afterwards? Is there anything to hide?
4) After knowing that with the baptism (in my Country) you become an adherent member of the local WT Society according to its Statute. Why discovering that casually only after the baptism on a Kingdom Ministry? Why not telling this to people before? Is there anything to hide?
These are all things I regret for not having known and/or done before my baptism!
