Impressive and informative story, Adelina. We have a routine here, that we watch the news together while having breakfast or lunch, so that they can ask questions and see what's happening around the world. Because at schools they would hear words or news and topics, they otherwise couldn't understand.
So we make sure they know the important parts why we tell them the necessary infos. And our kids like it that way. I see no fear in them...because we talk about these topics in a way how they can understand the connections etc. :-D
