My children became atheists before I did. I'll never forget, as a Christian father, the day my 15 year old son came to me and said that he had lost his "Notion of faith". I was so thick-headed in my Christian mindset at that time that the core of his comment didn't even hit me, and it wasn't until five years later when I de-converted that I even had a clue what he meant. My son taught me that what I had was a 'notion' of faith, rather than faith, and his comment was vital in assisting my evolution away from faith, and toward reason. If I have any considerable advice to give it would be to remain teachable. Your children may even be some of your greatest advisers. That, and hold them as often as they will let you, hold them close, because before you know it they'll be all grown up.
