The Medela Harmony manual breast pump set comes complete with Calma feeding device and nursing pads and has everything you need to start expressing and feeding baby. The 2-Phase Expression Technology is based on the natural sucking rhythm of the baby: Short, stimulating movements are followed by longer, more intensive ones, ensuring optimal milkflow. Its faster let-down and maximum milkflow significantly reduces pumping time - meaning you can express more milk in less time - and more comfortably. Nursing pads have been added to provide greater value and comfort for mum. Excellent for infrequent expressing and compact for easy travel.
