I have so far raised my daughter in the truth. She is 7 now.
You owe it to her to spare her the pain the religion can bring for so many.
The funny thing is, it's only after you leave that you realize that it takes more effort to keep going than to stop going. It sounds so obvious in hindsight, and you wonder what you'll do with all the spare time (but don't worry, it's easily filled with worthwhile pursuits)
