Wikipedia is the internet's library, and like any real library, the 'Adult Non-Fiction' section is right next to the 'Kids' section. It's an essential tool for the modern student, but it's not a playground.

For most families, it's the gold standard for school projects and late-night 'how big is a blue whale' debates. Just know that it is intentionally uncensored—it treats the user like an adult looking for facts. If your kid is younger, use it together or stick to Kiddle until they have the maturity to handle a stray graphic photo of a skin condition or a battle scene.
