2. GETTING STARTED

WILLOW FLANGE SIZE

CHECK YOUR FLANGE FIT

Choosing the right flange size is critical to successful pumping.
Make sure your Flange fits properly.

What’s your Willow size?

Your size for Willow might be different than the size you use for another pump!

Using the right size for your Flange or Milk Container can make all the difference
when it comes to comfort and the volume you get with Willow.

Visit willowpump.com/sizeme to check your size and see which
accessories are available

8

willowpump.com l text or call 1-888-WILLOW-3 Willow Wearable Breast Pump Generation 3 Instructions for Use

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.

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.

ALIGNMENT

To align, hold the Flange against your breast so you can see if your nipple
is centered in the Flange Tunnel. You may need to bend forward.

Aligning this way can help you confirm you’re aligned when you’re
learning how to use Willow.

g 3k Bring the Flange to

your breast, making sure
your nipple is centered
in the Flange Tunnel and
not touching the top,
bottom, or sides.

After you’ve aligned, look through the clear Flange to confirm your nipple is
centered before connecting the Pump. The tip of your nipple should
NOT touch the top, sides or bottom of the Flange Tunnel. If it does, try again.

18

Correct Alignment

Milk expression.

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 dierent Flange size (See
Section 2. GETTING STARTED - Willow Flange Size)

willowpump.com l text or call 1-888-WILLOW-3 Willow Wearable Breast Pump Generation 3 Instructions for Use

Incorrect Alignment

Try again.

19

When you’ve confirmed your nipple is centered, connect the Pump to the Flange.

g 3m Using your other

hand, bring the Pump
straight on to the Flange
until they connect.

g 3n Firmly hold

Pump against your
breast and press Play
to initiate latch.

INITIATE LATCH

a. Hold Pump rmly against your breast.
b. Press Pump/Pause button to initiate latch and begin pumping.
C. Continue to hold Pump rmly against your breast until it is latched.

Wait until Pump reaches Stimulation.

Trouble Initiating Latch? See Section 6. TROUBLESHOOTING.

Once you’ve learned how to align Willow, you may assemble the Flange and Pump
before you align. To assemble, bring the Pump and Flange together until they
securely connect. Then, align Willow by bringing the Pump to your breast, ensuring
your nipple is centered in the Flange Tunnel.

 Make sure your bra is keeping Willow pressed securely against

your breast, especially at the top of the Pump.

 Press Pump/Pause button, break latch and check alignment

(See Section 3. PUMPING - Alignment).

SUCTION LEVELS

›

Use the increase/decrease buttons

on the pump at any point during your

right for you.

›

Try the highest suction level that’s still

comfortable to help you get the most
from your session.

›

You’ll have access to the rst three

suction levels in Stimulation. Once
you’re in Expression and have pumped
about 0.5 oz. of milk, you’ll have access
to all seven suction levels.

›

The pump automatically increases your

suction by one level at this time, unless
you’re on the lowest setting (Level 1).

›

Check the app if you’d like to conrm

your suction level.

unique for each person and varies by many factors.

• Check nipple alignment, pause pump, break latch, and remove from breast.
Realign Willow as described below.

• You may not have the correct Flange size for Willow
(reference Section 2. GETTING STARTED - Willow Flange Size).

• Pause Pump, break latch, and remove Pump from breast. Realign Willow fully assembled (reference
Section 3 - PUMPING - Realignment Tips).

• You may also separate the Pump from the Flange to realign. To do this, perform Flip to Finish before
realigning (reference Section 4. ENDING YOUR SESSION - Flip to Finish). Then, center your nipple in
the Flange Tunnel and bring the Pump to your breast (reference Section 3. PUMPING - Alignment).

If experiencing excessive discomfort try the following

(reference Section 3. PUMPING - Alignment):

• Make sure to press Willow rmly against breast during Stimulation phase.

• Tighten bra to make sure Willow is held rmly against breast.

• Decrease suction level.

• Realign Willow (see above).
