7. The right size of breast shell
You will be able to express successfully if you have the right breast shell. If the breast shell is too big or too small, this may
cause sore nipples and may be painful. You should therefore use the right breast shell size for you or an appropriate insert.
The size is right if:
• there is around 2 mm space free around the nipple.
• the nipple moves freely in the funnel during expressing and can follow the rhythmic movements of the pump.
• there is no areolar tissue in the funnel.
• the milk flows and the breast feels soft all over after expressing.
If your nipple rubs uncomfortably on the inside of the funnel, use a larger breast shell. If the areola is also sucked into the
funnel, use a smaller breast shell insert.
Breast shells in size 24 mm and breast shell inserts in size 19 mm are included with the pumpset. Breast shells in size 27 mm
and breast shell inserts in size 17 mm are also available for this pumpset (we reserve the right to change this).
8. Storing breast milk
Keep the breast milk in a suitable container, for example a milk bottle (including the Ardo Bottle Set) or a milk bag (including
the Ardo Easy Store). Recommended storage time:
• at room temperature:
• in the refrigerator:
• in the freezer compartment:
ATTENTION: Do not heat breast milk in the microwave.
