Christmas I told my son that his mum and I bought him presents no mention of santa . His nan passed away and we told him she was on her way to becoming stardust . Otherwise god doesn't come up he's 3 so still early days . When his mum split from me her brother in law kept bringing up Santa and using the usual threats with behaviour and presents crap but I'm sticking to my guns and he realises I tell him the truth

As a young mom I didn't know any better and my children went to church and Sunday school but we were not glued to the seats even then. We adopted 6 other children and I home schooled. We learned about the religons of the world in our studies, we also attended various churches in our area of different denominations, and that was all it took. The kids got it with no problem. I didn't want my children mentally and emotionally handicapped either by some fool religion. They are all grown now and gone and doing fine - none are fanatics. Not sure if they go to any church or not but either way - fine.

I didn't become a Agnostic until after my kids were grown. Damn, I wish I could turn the time back.

We read and continue to read books.

What Do You Believe? [amazon.com]

When I was raising my children I was still under the clutches of organized religion so yes I did involve them but I did not force them. And I just explained to them that religion or faith or spiritual things were a very private thing and something that only they could decide.
And that their was nothing wrong with exploring all views and ideas and faiths.
Now that I’m raising grandchildren I have somewhat changed my thoughts.
I pretty much tell them how I feel about organized religion and why. And how I came to believe the way I do.
I do try and stray them away from church stuff of any faith.
I just try and keep them away from the Bible beaters of the world as much as possible. I tell them to use their own minds and talk about all aspects of belief systems.
I answer questions as they come up.
I try and not influence them but leave things open for discussion.
