Please don't call it the Mormon Church. Please call it the Church of Jesus Christ of Latter-day Saints in introduction and then after that the Church or the LDS Church. We need to emphasize who's Church we believe we are and it used to be that we didn't want to offend people who called us Mormon but we would like to get our title straight now that we are more respected.If I understand this correctly, are you suggesting children should be taken to other churches as well as the Mormon church so the children can know that Mormonism is true and others are false?
I think books about other religions is good enough, and if they want to check out other Churches I don't know... I'm not a parent and I don't know what it feels like to be a parent enough to answer that. Maybe another Latter-day Saint here can answer the question of whether to take children to other Churches.
