  "title": "Breast pumps described as copying a baby's sucking rhythm",
  "question": "Which breast pump is designed to copy a baby's natural sucking rhythm?",
  "answer": "Medela Pump In Style Pro: The maker says Pump In Style Pro has a pumping pattern similar to Symphony Maintain, 16 levels and a level 3 start. Blog check: The blog says the Pro has fewer suction settings and different stimulation and expression cycles than Symphony; this conflicts with the maker's stated 16 levels. Medela Harmony: no checked fact states that it copies a sucking rhythm; its listed use is Medela Harmony is a single manual breast pump for occasional pumping away from baby, travel, or backup to a double electric pump.",
