Inspired by baby’s unique combination of suckling and massage, Natural Motion technology powerfully combines suction and nipple stimulation for quick letdown and milk flow. This hospital-strength pump comes with minimal parts and an intuitive setup, a quiet motor and slimline design for discreet pumping, and you can personalize your experience with 8 stimulation and 16 expression levels. The closed expression system ensures milk does not get into the tubing. It also comes with a comfortable soft silicone cushion that gently adapts to the size and shape of the nipple, for nipple sizes of up to 30mm.
