How to Choose a Breast Pump

Pick a pump that fits your routine, comfort needs, and how often you will pump.

  1. Frequency of use: If you pump several times daily, prioritize hospital strength performance and durable parts over lower-cost models.
  2. Work and travel: Choose a rechargeable pump that can be used plugged in or cordless, and pack the extra flange sizes you need for comfort.
  3. Single or double: Double pumping saves time and supports supply for many moms, but single-mode can be useful when mobility is required.
  4. Comfort and fit: Start with the included flange sizes, and consider different sizes if you feel pinching or poor milk flow.
  5. Insurance and cost: Check your insurance or HSA for coverage before you buy, and compare warranty terms for long term value.
