The Pump In Style Battery Pack is intended for use with Pump In Style breast pumps (manufactured in January 2008 and later) ONLY.

The Battery Pack uses 8 AA alkaline batteries, or, for more consistent pump performance, use rechargeable batteries.

Each will provide approximately 2 hours of pumping time. It is recommended that batteries be replaced or recharged between the 10th and 12th pumping session.

Inspect tubing after each pumping session. Clean tubing if there is any sign of condensation and/or milk.

In the past it was thought that mothers needed to make more and more milk as their babies grew.  Scientists now know that a healthy milk supply remains fairly constant over the six (6) months of exclusive breastfeeding.  Your baby will take the amount he needs.

During the early weeks, babies eat very frequently and grow very quickly.  By day 10-14, babies should regain any weight they lost after birth.  For the next few months babies will gain about an ½ ounce to 1 ounce a day. 

Around three (3) to four (4) months, a breastfed baby’s rate of grown begins to slow down.  Your milk supply will continue to satisfy the baby until it is time to introduce solids at 6 months.

Be the end of the first week of life, women who are breastfeeding one baby normally make between 19 to 30 ounces of milk each day.  Infants between one (1) and six (6) months of age normally drink an average of 19 to 30 ounces a day. 

An average size “meal” for a baby is between three (3) to five (5) ounces of breastmilk.  Formula is harder to digest and less well absorbed.  Formula fed babies may need larger feeds.  Consult your healthcare professional for advice.

• You can safely store your breast milk for up to 10 hours* with Pump In Style Advanced and Freestyle breast pump cooler bags.   
• Direct exposure to the sun, like leaving the cooler in a car, severely reduces the cooling effectiveness. 
• Breast milk is safe stored in a cooler at/or below 59 degrees for up to 24 hours.
• The liquid inside the cooling elements is water with food grade dye. The liquid is non-toxic.
• Medela does not have recommendations for storing breast milk with dry ice. Consult a lactation consultant or healthcare provider for further information.

While traveling outside the U.S. with Pump In Style Advanced, we recommend using the battery adaptor or Portable Vehicle Adaptor (sold separately). The Portable Vehicle Adaptor may not work with all vehicles. Please check the owner's manual for compatibility with 12-24 volt input.

The Pump In Style Advanced power adaptor is a linear power supply that is designed for use with standard U.S. outlets. Use of the current adaptor outside the United States or use of a different adaptor may result in breast pump motor damage and unpredictable operation.

Using a universal power adaptor with Pump In Style Advanced may result in breast pump motor damage and unpredictable operation.
