The Swing Breastpump is the only single electric personal use pump with breakthrough 2-Phase Expression® technology for maximum milk flow. First researched and developed for hospital breastpumps, Natural Expression is an advanced pumping pattern that mimics a baby's nursing rhythm by pumping in two distinct modes.
· Let-down mode: Simulates your baby's initial rapid suckling to initiate faster milk flow.
· Expression mode: Simulates your baby's slower, deeper suckling for maximum milk flow in less time.
