  "question": "Which breast pumps shut off automatically or protect against milk overflow?",
  "answer": "Medela Symphony PLUS® Breast Pump: The sources disagree on automatic shut-off: the store says the pump shuts off after 30 minutes of use on battery or mains power, while Medela’s manual says it shuts off after 30 minutes without any adjustments. A membrane separates the separately sold pump kit from the pumping mechanism and protects the mechanism against milk overflow.\nMedela Sonata Smart Breast Pump: It uses closed-system overflow protection.",
