Because it does not require batteries or an electrical source, the Lansinoh Manual Breast Pump is a portable and practical solution for breastfeeding women who want to express themselves discreetly and comfortably while on the go. A simple switch at the top of the handle allows you to switch between the letdown and expression phases of breastfeeding, making it straightforward to use. At the commencement of the feeding process, the letdown phase resembles your baby's natural sucking manner. The expression phase mimics your baby's longer, slower draws while breastfeeding. The ergonomic handle allows you to use the Lansinoh manual breast pump with one hand, reducing wrist strain. It also has a ComfortSeal cushion, which makes pumping more efficient as well as more comfortable. A one-of-a-kind stand is included to keep the pump bottle stable during and after expression.
