Raising Children Wiccan-- is it possible? Misconception? Or what?

It does sometimes happen but i have heard a rule they wont indoctrinate you into wicca untill youre 18 and have studied it one year and one day (im assuming this was to avoid lawsuits from christian parents who had kids in wiccan covens and groves). Yet of course these rules are bent plenty of times. I think wiccans arent as into forcing beliefs on others (which is part of the religion even to avoid that)
