Rmended by International Board Certified Lactation Consultants, the hospital strength Evenflo Feeding Advanced Double Electric Breast Pump is the perfect solution for moms with everyday pumping needs. The newly designed quiet?hush? motor allows for discreet pumping anywhere. Multiple power options - AC Adapter, AA Batteries* and Evenflo Feeding Car Adapter*? gives you the flexibility and discretion to pump at home, work, school or on-the-go. The independent speed and suction controls allow you to mimic your baby?s nursing behavior and trigger multiple letdowns (milk releases), helping you get the most milk out of each pumping session. To help keep you comfortable and pump more milk, multiple flange sizes are included and additional sizes are sold separately. The closed system design helps prevent milk back up in the tubing and pump motor to keep parts clean, dry, and functioning properly. *Sold separately Gender: unisex.
