This breast milk expression kit mimics a baby's suckling and gently stimulates breast milk production, helping to extract more milk in a more natural way. The natural suckling effect is achieved via a combination of active massage and suction from the motor. The design draws on an understanding of a baby’s natural suckling – how they latch onto their mother’s nipple and areola and use peristaltic tongue movement to stimulate milk expression. The result is a new-generation cushion that can adapt to different breast shapes and massage effectively at the position of the mammary ducts.
