How do parents hide the war in Ukraine from their young children?
Young children may not even know about death yet, so it seems that parents worldwide would try hard to hide this war from them.
I doubt they have to hide anything? Kids aren't much known for watching the news. I'm not sure why it would need to be hidden though. That kind of sheltering doesn't strike me as productive.
Why hide it? Tell them there are places in the world that people are not as lucky and mean people do unjust things. You don’t have to fixate on it but you might as well introduce them to the idea that the world isn’t perfect and people have to work hard and sacrifice to lead a first world lifestyle.
I saw Ukrainian woman interviewed on TV who said that she tells her children that the explosions are fireworks.
You don't. You teach them about real life.
