I work with children and I'm used to a barrage of questions from the inane to the stupendous. It's so easy to shrug off the 47th "But why?", but it can actually be interesting to at least try to answer - "We breath because we need Oxygen... because we convert glucose…"
Eventually you inevitably end up at the metaphysical or epistemological - "because if truth wasn't…"
The mind of a child is (and ought be) infinitely inquisitive!
*besides factual questions and even in that case, I still ask them to guess first
The other part of me thinks kids have a lot to learn, and asking why is a good way to get there.
Indeed, there's a reason why it has become an accepted and well-used tool in the management toolbox.[1][2] It's something we shouldn't stop doing as adults.

Encouraging children to ask why is not only the most kind thing you can do for them, but also the rest of the world.
