If you visit a Mormon service on Sunday, the first thing you'll probably notice is the mid-level roar of all the child noise going on in the pews.
Children and families are a central part of our beliefs, which you can see (and especially hear) on Sundays at church. We don't have the kids leave for a separate "children's sermon" or spend the hour playing in a nursery. We all sit as families in church, together.
Some days I don't hear much of what's said, or I join the unofficial "parents' club" in the foyer because my kids are being rowdy, but I'd never dream of not attending church as a family.
I take my kids to church because out of all the things I want them to know, this is the most important. It's OK if you disagree, but I think it has the greatest potential for lasting happiness of anything I could teach them.
