2. GETTING STARTED
FLANGE SIZING GUIDE
1. Stimulate your nipple so it’s erect.
2. Hold a dime, nickel and quarter in front of your nipples to compare the diameter of the
base of your nipples (not the areola) to each coin.
3. Determine your flange size using the chart below.
TIPS: It can be helpful to use a mirror, sele and a
side view to get the best estimate of your size.
Do not squish the coin against your nipple
as this can distort your size.

CHECK YOUR FLANGE FIT
Choosing the right flange size is critical to successful pumping.
Make sure your Flange fits properly.
Your flange size may fluctuate with birth, breastfeeding, and pumping.
We recommend you revisit your flange fit from time to time.
Too Small: During
pumping, some or
your entire nipple rubs
against the side of the
flange tunnel.
Too Large: During pumping,
more areola is drawn into
the flange with your nipple.
Your areola may rub against
the side of the breast flange
tunnel.
Good Fit: During pumping,
your nipple moves freely in the
flange tunnel. You see space
around the nipple, and little
to no areola is pulled into the
tunnel with the nipple.

Willow Wearable Breast Pump 2.0 Instructions for Use
GET THE RIGHT BRA

pressed firmly and securely against your breast.
Pick the right bra:
Full coverage

Made of stretchy fabric
No underwires or padding
If it feels like Willow will shift when you move,
tighten the straps or pick a different bra.
No gaps!
The blue thumbpad on the

ALIGNMENT
a. Open bra ap, ensuring fabric is out of the way. Stimulate your nipple.
b. Determine the direction your nipple points.
Nipples point in different directions (straight, up, down, to the side).
TIP: No two nipples are the same. The direction varies from
one side to the other and from woman to woman.
IMPORTANT: Correct nipple alignment is key to comfort, expression and
performance. Nipple must be positioned correctly in Flange Tunnel before
pumping to avoid discomfort. If you still experience discomfort even with
proper alignment, you may need a dierent Flange size. See Section 2.
