was born? In the year? At three? At the five? How to determine when the child is already aware of this information? Most importantly, he is interested in it. And it's not about religion, it's just early to talk about it, and then somehow it didn't have to talk about it.

It is surprising, but how many people hold their children for idiots. Oh, tell the child in the year that the grandmother is my mom’s mom, the gygigans, you’re cha, he’s nigat to that! It is funny.
I always respond to the children as detailed and honestly, clearly, in the language as simple as possible. As a result, by their 4 years, they sometimes have to go into the encyclopedia, because the complexity of requests increases. Well, by 10 they are already smarter than most of the commenters here :)
