I know a few good pastors out in California, including Pastor Dan Hyde. Every book I have read by him has been profitable. Right now I am reading his short book  on children in worship, The Nursery of the Holy Spirit.  Here is a great paragraph explaining why our children need to be in worship with us. All punctuation is his except brackets and I have removed footnotes.

With a renewal in biblical doctrine in many evangelical circles today, for example, among “New Calvinism,” it is a great time to reevaluate our practice [of excluding children from worship] and to ask how we can become more “children-friendly” as churches in the area of worship. This is also a great time to do this given the content [context?] in which we live, as our children are being assaulted in their faith more than ever before. Even before many children are born they are assaulted by “Pro-Choice.” Our culture is more and more seeking to allure children into a worldview of hedonism, materialism, and narcissism. The church, therefore, needs to be a refuge for children from the earliest age. One practical expression of this is  in welcoming our children to join us before the throne of God’s grace in worship, giving them a meaningful place in the church. As the church education professor, John Westerhoff III, has shown, the biblical example of three generations in the church’s worship results in interaction and sharing among generations as well as a sense of experiencing the whole community of faith. The children of believers, therefore, are children of the church and belong in the Holy Spirit’s most child-friendly nursery-public worship.
