get ready to align
To align Willow, you’ll need to rst determine your nipple direction. No two nipples are alike.
Pay close attention to the direction your nipples point (straight, up, down, to the side).
Remember your nipple direction? Bring the Flange to your breast from
the same direction, centering your nipple in the Flange Tunnel.

Aligning Willow correctly is so important. Look down and to the sides to
make sure your nipple’s centered!

While pumping you are going to hear several dierent sounds that indicate which phase you are in.
The Pump transitions from Stimulation to Expression
when the Flextube™ and Flange are full of milk.
INITIATE LATCH
Louder, slower sounds
The Pump is latching.
Remember to hold
Willow securely
against your breast.
STIMULATION
Short, quick sounds
You will experience
let-down and milk will
start to ow. Look at the
App to see your progress.
EXPRESSION
Slow, quiet sounds
Many women transition within 5-7
minutes, but this can vary. Suction
level starts at 1, but you can adjust to
your desired level. Note: you cannot
go back to Stimulation phase.

check your volume
Use the Willow App to keep tabs on your progress.
Greater than 0 oz means
milk is flowing and
you have a good latch
(this should happen with
5-7 minutes).
If you do not transition to Expression after 5-7 minutes, you may need to realign.

flip to finish
After you break latch, you will notice there is still milk in the Flange Tunnel.
