Reporter: It's the Neitzel family Christmas gift, that quite literally, keeps on giving. Alexa? Hello. Reporter: Forget writing a list to Santa, Amazon's voice-activated device, echo dot, makes shopping super easy. Maybe too easy. All 6-year-old Brooke Neitzel had to do, was make this simple request. I just asked her if she could order a dollhouse and some cookies. She said do you want this and I said yes. I get an Amazon notification that says your order has shipped. I thought that's interesting, I've not made an order! Reporter: Alexa delivered. Four pounds of sugar cookies and a $160 dollhouse. Today, they donated the dollhouse to a local children's hospital. Alexa teaching a lesson to kids and parents tonight. Linsey Davis, ABC news New York City. Thank you for watching tonight. I'm David Muir. I hope to see you right back here tomorrow.
