Xanthippe, I didn't pick up on that, sorry.
I hope that he is here and that he takes your advice. Having children is a very important time to reflect on what one hopes and plans for that child. Certainly the JW religion restricts many things that we may otherwise aim for on behalf of our children.
I know of some JW families that are not preventing their children from higher education but when the father is in a prominent position they are not likely afforded this opportunity. The father can lose his position if he allows his children to recieve higher education.
I don't know if your nephew does hold any positions in the religion and if he does, or may in the future, he should consider how much time this will take away from enjoying a full family life. My father was an elder and we saw so little of him, he was usually sitting in his office and working on various JW duties, including study, public talk presentations and various other responsibilities. We had very little fun times, just doing things together.
We weren't allowed to do any out of school activities like sport and it was probably just as well as he would not have had the time to drive us around let alone watch us.
It is worth the time to investigate the religion, both its past and its beliefs as he now has the responsibility of teaching his own child.
