  "title": "Why a breast pump may lose suction or feel weak",
  "question": "Why does a breast pump lose suction or feel weak?",
  "answer": "MEDELA Freestyle Flex: Experiences are sharply divided. Many users find the shields gentle and comfortable and report quick, effective expression, while others report weak or declining suction, especially during double pumping. Multiple users report motors or charging systems failing within days, weeks or months, sometimes across replacement units. Other users report months or years of satisfactory use, so longevity appears inconsistent.\nMedela Harmony: Results vary sharply: some users report fast, high output that matches or beats electric pumps, while others obtain little milk after long sessions. Use rapid presses on the short handle side to stimulate flow, then slower presses on the long side to express; the user controls speed and intensity.\nMedela Harmony® Breast Pump with PersonalFit Flex™: Medela positions it for occasional pumping, travel or backup use; frequent pumpers may be better served by a double electric pump.",
