I hear you - I have had the most success when I was able to focus the person that I was talking to on to one particular topic and once I discovered what interested them I then proceeded to deep dive with them.
Truth be told, it took you (and me) many years to awake - if your children are extremely lucky they may get there in 10 years. Respectfully, it your responsibility to be there every step of the way!
While I can't (and would never presume) to understand your unique situation) it may simply require some love, patience and time on your part.
I hope that my comment has helped - all the very best to you and your children!
Thanks!
