SHHHH!!! BE QUIET!!!!

We have a very difficult time with Ian in church. We don't know how to keep him quiet. He is so loud and will NOT whisper. He does however make the people sitting around us laugh. Like today we brought our file folder games to try to help keep him quiet but when we pulled it out he yelled "WHAT IS THAT BIG BOOK YOU HAVE". The people sitting in the row with us laughed. Then he proceeded to announce everything he was putting bacon the pages. Now everyone around us knows that Ian knows his animals and all their sounds too. We did chuckle when he called the snake and angry worm. He also likes to sing the ABC's during the sacrament which makes everyone laugh as well, which is not a good thing. We try to keep him quiet but just don't know what to do. We have finally got him to fold his arms during the prayers which we feel is a major accomplishment.
