Finding Your Best Flange Fit
Finding Your Best Flange Fit
Finding the best Breast Flange fit cannot simply be done
by measuring your nipples because some nipples stretch
more than others under suction. You can estimate your
size, but some trial and error may be needed for you to
optimize your comfort and milk output. Experiment to
find the right fit and keep in mind:
• You may need a different size than the Flanges provided.
• You may need a different size for each nipple because
no one is perfectly symmetrical.
• You may prefer higher suction, making Flange
comfort crucial.
• Your nipple may expand in diameter and length while pumping
and may change over time, so keep all of your sizes.
Flange is too small
for the
nipple to move freely in and
out of Flange. May cause
rubbing or chafing.
Comfort is key!
It may take a
few tries to find what works. The
Breast Flange size is measured
across the opening that your
nipple fits into.
Flange is too big
allowing
too much breast and areola
tissue to be drawn into Flange.
May cause bruising.
Flange is correct size
when
the nipple moves in and out
of the Flange freely.
Choosing Another Size
Use a ruler or coin diameters
to estimate your erect nipple
base size. Choose the nearest
size Flanges or Fitmie inserts
that are slightly larger than
your nipples.
Internal Diameter
is measured across the opening.
SlimFit Fitmie soft inserts for pumping comfort
are available in sizes 15mm – 28mm and sold
