Great for when you are away from an outlet or on-the-go, the lightweight and compact design makes the Evenflo Feeding Advanced Manual Breast Pump great for discreet milk expression. To help keep you comfortable and pump more milk, multiple flange sizes are included and additional sizes are sold separately. The pivoting pump handle is easy to hold in either hand and rotates to allow for multiple pumping positions. To pump, simply start with a fast, short pumping motion to help stimulate your first milk release. As milk starts to flow, transition into a slower, longer pumping motion.
