My niece and her husband involve their four young children in watching general conference in a teaching way. They make a tent, using a blanket attached to the stair railing and supported by kitchen stools and a broomstick. They call it their "King Benjamin tent." (Mosiah 2:5-6). The tent faces the TV set so they can, as a family, listen to the words of the prophet.
During the sessions of conference, the children sit in the tent and draw pictures and otherwise play quietly. This past conference, at least two of the children had their Captain Moroni swords fastened to their sides.
They felt this would be a good way to teach a Book of Mormon story as well as help the children understand that conference is special. Virginia Havens, Salt Lake City, Utah
