PRACTICE
Before your first pumping session, we recommend that you practice
Alignment with just the Flange.
CHOOSE THE RIGHT FLANGE SIZE
In addition to proper alignment, choosing the right flange size is critical to successful pumping.
If you’re not sure what your flange size is, visit our website: www.willowpump.com
Your breast 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 breast 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
breast flange tunnel. You see
space around the nipple, and
little to no areola is pulled into
the tunnel with the nipple.

7B. PUMPING
• Wear a nursing bra that keeps Pump securely in place. If it feels like Willow will
shift when you move, adjust the bra straps or pick a different bra.
• Do not slide Pump directly into your bra; follow step-by-step instructions.
• Disconnect from Charger before use.
• Willow should only be worn (latched) while actively pumping. You should break latch
and remove Willow once you have finished pumping.
• Consult your healthcare practitioner to understand how long you should pump for.
Willow turns o automatically after 25 minutes.
1. TURN ON PUMP Press On/Off button until Pump lights up.

2. ALIGNMENT
TIP: When double-pumping, get to Stimulation Phase with one Pump
before putting on the second.
a. Open bra flap, 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 dierent Flange size.
Contact Willow Customer Care to make sure you have the proper size.

c. Bend over and bring the Pump to your breast in the direction your nipple points,
centering your nipple in the Flange Tunnel.
Increase success by...
The tip of your nipple should not touch the top, sides or bottom of Flange Tunnel. If it does, retry.

your breast with an underwire hold,
bring the Pump to the breast.
fig 2c Then hold Pump firmly against
breast and sit upright taking
care to prevent Pump from shifting.
TRY AGAIN
fig 2d Note: If your nipple is
touching the Flange
tunnel even with
proper alignment,
you may not have the
correct Flange size.
ONCE YOU START PUMPING, YOU MAY NEED TO
REALIGN IF YOU...
• Experience excessive discomfort or pain that is not alleviated by pressing Willow
firmly against your breast or adjusting suction level
• Do not reach Expression phase within 5-7 minutes
• Experience low milk volume
• See air in the Milk Bag after pumping
TO REALIGN
• Pause Pump and break latch (reference Section 7B. PUMPING - Break Latch).

not yet pumped into Milk Bag.
• Bend forward, center nipple in Flange Tunnel, press Pump to breast, sit up and
initiate latch by pressing Pump/Pause button to resume pumping (reference Section
7B. PUMPING - Initiate Latch).
• Do not lift or move breast while Pump is latching.
