Our church has classes for the kids, based on their age group, and the few times they have everyone in the service they make a point about not being bothered by any noise from the kids.
Happy birthday Leonore!
Our church used to have a creche for the youngest, while the older ones could go to the so called Kindernevendienst (they would attend the opening of the mass; then would assemble and go to another room or building; there they would discuss the topic of the service of that day on their level. In that process they would form their intercession. The children would return to the service, and one of the children would read their intercession at the altare. As part of all the other intercessions).
