Amazon Echo's voice assistant has gained a handful of new skills, including the ability to answer questions about your kid's health. It now has access to KidsMD, a new app powered by info prepared by doctors from Boston Children's Hospital. You can ask it about various symptoms like fever, coughing or headache if your kid's experiencing any, as well as age- and weight-specific dosing guidelines for various medications. Just say "Alexa, ask KidsMD about [symptom]/dosing." The feature sounds especially useful if you're frantically dealing with a sick child and don't have time to pick up a phone to do a Google search.
