Too Small
• Nipple rubs along
side of tunnel
• Try a larger size
3. Should you try a new size?
• Does your nipple rub sides of tunnel, to the point of causing discomfort?
• Do you see excessive areola being pulled into tunnel?
• Do you see any redness?
• Is your nipple or areola turning white?
• Do you feel unexpressed milk after pumping?
If you answered "YES" to any of these questions, consider trying a new size by following the
measuring instructions above.
If you are still unsure if you selected the correct size, see a lactation consultant, breastfeeding
specialist, or visit MedelaBreastshields.com for assistance in choosing the right size breast shield.
Caution
• While some discomfort may be felt when first using a breast pump, using a breast pump
should not cause pain. If you are unsure about breast shield sizing, please contact a health
care professional or breastfeeding specialist who can help you get a proper fit.
• If you are experiencing discomfort at the base of the nipple due to rubbing of your breast
tissue against the breast shield tunnel, use of a lubricant such as Tender Care Lanolin may
be beneficial.
