6.2 Optimising the breast shield size
• Start with the breast shield that came with your pump, or the size determined by measuring.
• Centre the nipple and gently hold the breast shield against the breast.
• Adjust for maximum comfort vacuum (refer to
chapter 9
) to achieve optimum suction level.
• Refer to the images below while pumping in the expression phase (after the stimulation
phase).

Areola
• The nipple rubs along the
side of the tunnel.
• Try a larger size.
• The nipple is centred and
moves freely.
• The nipple and excessive
areola are pulled into the
tunnel.
• Try a smaller size.
Reasons for trying a new size
• If your nipple rubs against the tunnel sides to the point of causing discomfort.
• If excessive areola is being pulled into the tunnel.
• If there is any redness.
• If your nipple or areola is turning white.
• If you feel unexpressed milk after pumping.
If any of these conditions occur, consider trying a different size by following the measuring
instructions above.
In case you are still unsure if you selected the correct size, see a lactation consultant or
breastfeeding specialist.
