I think you would probably like a more modern church - pentecostal often scares alot of people, but happy singing, etc is what we do best! My church has a large number of children and do children's church - children stay in for worship - singing and communion then go out to their own activities - usually a simple bible story, drawing, art activity, etc. Usually something yummo to munch on, a few games etc.

Many churches will allow you to send your children along even if you aren't keen yourself.

Try out a church of christ too as they aren't as loopy as us pentes!!
