at my church we have a "cry room" for the noisy ones. My problem with my DS is he can't sit still for too long often at church so we (DS and either DH or me) often head out to the cry room or the foyer for a bit of a walk around/play. The cry room has a nice collection of toys & books in it - parents/caregivers are expected to supervise own children. It also has the service played in there as well through some sort of amp although they've had a few issues with it lately. Most members at my church don't have an issue with kids of young ages making a bit of noise during the service.
