When Iit comes to Video Gamesvideo games, the main point to keep in mind is that they are not a Baby Sitterbaby sitter. Just like with artistic expression or physical sports, the important thing is keep engaged with them. If you don't enjoy the games themselves, just listen to the child. If they are having a hard time with a particular spot, just be there for moral support. All a video game is at that age is a toy as any other. It wont cause any more harm or help any more than watching TV or a movie.
