Impulse, naturally better by design. Specially designed for the health of mom and baby during breastfeeding, Impulse is the only complete line of breast pumps, breastfeeding accessories, skincare products, and nutrient supplements. These products are developed and produced by a team of lactation consultants and moms, to naturally support the positive bond between moms, babies and breastfeeding. Simplisse Manual Breastfeeding Companion's new advanced design conforms and moves with mom's breast. There is no tugging, no pinching and no friction. This design eliminates the "suck-and-release" technology found in many other pumps. It naturally elicits milk rather than extracting milk. The baby face flexible breast cup is highly pliable and flat like baby's face, emulating the baby's suckling motion and feeding pressure. It promotes soothing milk flow for enhanced milk productivity. Dishwasher safe, BPA free including collection bottle.
