This mobile breast pump on show at CES does no't use any cords or bottles, allowing new mothers to express milk without connecting to a power socket or getting undressed. Breast pumps, which draw milk from a woman's breasts by suction, typically involve bottles and tubes, all hooked up to a relatively robust machine.\r\nBut by conducting its own research, Willow found that 89 per cent of mothers wanted a hands-free option, and 67 per cent said their ideal pump would no't require them to undress. Willow's teardrop-shaped machine sits discreetly underneath a woman's bra. It quietly collects milk in a pouch stored inside the device – meaning women no longer need to be tethered to the wall or undressed while they express milk. The rechargeable device is also connected to an app via Bluetooth. The app tracks milk volume and time, as well as the points at which the user tends to express milk.
