More and more parents are falling in love with Amazon's virtual assistant Alexa, that's the speaker-like device that gives you voice control over almost everything you can think of.

It responds to the name Alexa and you can ask her all sorts of things: 

"Alexa, put Cheerios on my shopping list."

"Alexa, turn on NPR."

Or if you need to entertain the kids... "Alexa, play 'Let it Go'."

Or "Alexa, tell me a joke."

To work, Alexa is recording all the voices in the house. But that's raising privacy concerns, especially as it relates to kids.
