When I DA'd my kids were ages 11, 9, 7, 6 and the older two were pretty confused by my about face on god and religion. I ended up raising a passel of atheists now ages 25, 23, 21, 19. Great, hardworking (2 in college) honest, honorable, delightful members of the human race. (do I sound proud?) They are open to possibility and we have many lively discussions about life beyond. They have however taken some guff about not having a religion and never having been baptized. If I had it to do over, I'm not sure but I would lean towards doing it the same way. Their friends eyes bulge in disbelief when they find out that they were never baptized, but the kids are able to defend themselves, I hope I haven't robbed them of anything, I don't think I have but a Mom's guilt reflex is never at rest.
as far as any of them become dub's well my eldest son-25 has informed me that he would be dismayed (putting it lightly) if I ever went back, the rest concur, so I guess I have no worries on that front.
