Like every Medela product, the award-winning Pump in Style is designed to make breast milk feeding easier, so moms can feed their babies with breast milk for longer. The Pump in Style Advanced Starter Set is a daily use breast pump featuring 2-Phase Expression® technology. The modular pump allows mom to build a customized system that fits her lifestyle.
2 Phase Expression® technology by Medela: 1. Stimulation Phase – when babies first go to breast, they suck fast and light to start milk flowing. 2. Expression Phase – after milk flow or “let-down” starts, babies breastfeed with a slower, deeper suck, bringing out more milk faster.
