Children should not have to be “realistic” much of the time. That’s how they learn. They have the rest of their lives to be realists. It’s not as much fun. Children learn by play.
My dad was a radio operator in the Coast Guard in WWII. He was at Normandy, Iwo Jima, Okinowa. Didn’t talk much about any of it. My uncle was at the Battle of the Bulge. My cousin says she has a Nazi flag that he took.
