cooler bag
• Do not microwave breastmilk.
Microwaving can cause severe burns
to baby’s mouth from hot spots that
develop in the milk during microwaving.
(Microwaving can also change the
composition of breastmilk.)
• If the ice pack is frozen solid, it will
safely cool your breastmilk for up
to 12 hours in a room temperature
environment.

5.1 Preparing breastmilk
• Thaw breastmilk overnight in the refrigerator. Thawed breastmilk is safe in the
refrigerator for 24 hours. Do not refreeze thawed breastmilk.
• Quickly thaw breastmilk by holding the bottle under warm running water.
• Place the sealed bottle in a bowl of warm water for 20 minutes to bring it to body
temperature.
• If you are adding expressed breastmilk to a container of already frozen breastmilk,
make sure to add a lesser amount than the already frozen amount.
5.2 Feeding breastmilk
It is recommended that breastfeeding is well established prior to bottle feeding your
baby.
• Always inspect the bottle, nipple and other components immediately before and after
each use. If nipple appears cracked or torn, discontinue use immediately.
• To prevent possible choking hazard, test strength of nipple by pulling on bulb portion
of the nipple.
• Do not attempt to enlarge the nipple hole.
• Infants must not be bottle fed without adult supervision.
• Nipple should not be used as a pacifier.
The Pump In Style Advanced cooler
bag requires one contoured ice
pack (#87092, included) for cooling
up to four 5 oz bottles of breastmilk.
• As soon as you are finished
pumping, place the breastmilk
bottle or breastmilk storage bag in
the cooler bag with the ice pack.
• Transfer breastmilk bottles or
breastmilk storage bag to the
refrigerator or freezer once you are
home.
