Does Alexa have a child safety feature that can be enabled to prevent children from using Alexa? My point is that Alexa is a pretty intuitive to use, children won't have see observe their parents using the device more than a few times before they're able to trigger Alexa.

So either Alexa, and other digital assistants, should have a way to prevent "unauthorized" use, or we might need to consider if it's a safe device for families with small children. Perhaps simply being able to disable answers based on internet searches.
