9. Breast Shield Sizing
Caution
• While some discomfort may be felt when first using a breast pump, using a breast pump
should not cause pain.
• If you are experiencing discomfort at the base of the nipple due to rubbing of your breast
tissue with the breast shield tunnel, use of a lubricant such as Tender Care
be beneficial.
• For assistance with correct breast shield sizing and comfort please visit
www.medelabreastshields.com or see a lactation consultant / breastfeeding specialist.
Correctly fitting breast shields
Properly fitting breast shields will ensure comfort and efficient milk expression.
To determine if you have the correct size, look at the following diagram:
• The nipple should be centered in the tunnel of the shield.
• The nipple should move freely without rubbing when the pump is turned on.
• Minimal or no part of your areola should be pulled into the tunnel of the
breast shield.
• You should see a gentle, rhythmic motion in the breast with each cycle of the
pump.
• After pumping, your breast should feel less full with no areas of hardness.

10B. Preparing breast milk
Nipple
Caution
• Do not thaw frozen breast milk in a microwave or in a pan of boiling water.
• Do not microwave breast milk. 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 breast milk.)
Areola
• Thaw breast milk overnight in the refrigerator. Thawed breast milk is safe
in the refrigerator for 24 hours. Do not refreeze thawed breast milk.
• Quickly thaw breast milk 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 breast milk to a container of already frozen
breast milk, make sure to add a lesser amount than the already frozen
amount.
10C. Feeding breast milk
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.
