Yes, you can be proud of your kids. Your mom has the problem accepting reality, not you. I have been there, done that, and I agree with folks who suggest telling your kids the truth, matter-of-factly, with as little judgment as you can. For providing a religious background for my daughter, I joined the Unitarian Universalist Church and enrolled my daughter in the Religious Education program, even though I'm an atheist. It's usually free, but they do like for parents to contribute in some ways, if possible (as with most such programs). I have never regretted doing it and didn't do it religiously; I just knew that when I felt like going to church and spending a little time with some very nice people, my daughter would be learning a little about our cultural history from some relatively balanced and caring folks, in an age-appropriate, non-judgmental setting (so completely different from what I was raised with at the Kingdom Hell). I also made sure that people from the church understood that UUism was my best antidote to JWism. (In fact, it is at the complete and absolute opposite end of the religious spectrum from the JWs). I was glad to see that everyone I encountered was able to understand and fully supported me and understood my motivation without question or judgement or preaching. If you enroll your kids in any kind of RE program at any church, it is probably a good idea to inform the teachers there of your situation; they too may have gentle ideas for handling and explaining things you want your kids to understand. I think it is also important you know they are not badmouthing your mother or her religion to the kids. Good luck with your endeavours!
