Some Moms have told us that they have been able to obtain full or partial reimbursement for their Willow through insurance. Each insurance company has its own policy regarding reimbursement. Once you have your pump, the next step is to check with your plan administrator to see what you qualify for. We hear again and again that Moms don’t let insurance companies stop them from being hands free and getting time back in their day.

Sizing with Willow is different than sizing with traditional wall pumps. 

It’s important to measure to make sure you have the right size for Willow - when your pump flange fits properly, you get more comfort, a better latch and more milk output. To determine your nipple size we suggest either printing our Sizing Tool or using one of these free ruler apps for iOS or Android. 

 

Size with a Mobile App

To find your flange size using a mobile ruler app, first stimulate your nipple so it perks up.  With the app open on your screen, place your phone screen perpendicular to your nipple so you can look down at your nipple against the screen.  

One edge of your nipple should line up with the zero on your screen.  Slide the measurement bar on your screen to the opposite side of your nipple - that's your nipple measurement!

Now that you have your size, we suggest you use a flange that's 2 - 4mm larger than your nipple measurement. 

Size with our Printable Tool

To size with our printable Sizing Tool, cut around the outside of the tool and fold twice. 

Stimulate your nipple to perk it up.  Slide the paper ruler against your nipple until it is nestled in the corner.  Taking a picture or looking in a mirror may help you to see your nipple measurement. 

Use a flange that is 2 - 4mm larger than your nipple measurement.

In most cases, correcting one of these 3 things will improve your pumping volume. 

Size - Have you measured your nipples and are you wearing a Willow flange or container insert that is 2 - 4mm larger than your measured size? Both of these factors are critical to milk output with Willow. Follow the guidelines for sizing here to get the right size for you.

Bra - Wearing the right bra can help with volume. Your bra should hold the pumps firmly to your breasts for greater comfort and volume. We recommend wearing Willow with a full-coverage nursing bra that’s stretchy and has a flap. We have several recommended bras that work well with Willow here.

Alignment - It is important to line Willow up with your nipple before latching. Study the direction your nipple points and elongate or stimulate your nipple so you are sure of the direction it will point under suction. Keep trying, most moms master this in 5 - 7 sessions. If it is not comfortable or no milk is flowing, remove and realign.

How do I check if milk is flowing?

Sizing is even more important with Willow as we create a latch (not a pull and release like traditional pumps), so the nipple needs to have enough room to express milk but not so much that there is no stimulation. Let’s get you sized correctly. 

Head over to our Nipple Sizing Guide - please don’t skip this step. You need to wear a Willow flange or container insert that is 2 - 4mm larger than your measured size for greatest comfort and volume.

My Pump isn't moving to Expression, any tips?

How can I make pumping more comfortable?

Willow uses lights and alerts to tell you what’s going on. Here’s what they mean: 

Orange blinking light - Use our interactive helper tool.

 

Interactive Helper Tool

 

Close & Open Pump Alert - most often the Flextube grips are not in the pump sockets. Troubleshoot with our helper tool.

Flush Through Container Valve or Attach Bag - in most cases the valve is not laying flat inside the dial or there is soap or milk on the valve preventing latch. Troubleshoot with our helper tool.

 

White and orange blinking lights - Willow cannot latch, try again and remove any clothing, bra or material that may be between your skin and Willow.

White pulsing - Willow has paused, you’ve pumped for 25 minutes. To continue press Pump/Pause.

White solid - Congratulations! Your milk bag is full, add a new bag or empty your container to continue pumping.

Battery lights

Green - enough charge for 2+ sessions

Orange - enough charge for 1 session

Red - inadequately charged for a complete session

How do I enable app alerts and notifications?

My pump stopped pumping but I didn't get an alert.

Please clean all accessories after each use. If there’s no space to completely clean, rinsing after use makes cleaning easier later on. Dried milk is challenging to remove. 

Here’s how we recommend cleaning:

Flange, Flextube™ and Container - after every use, disassemble all parts and wash by hand or pop the parts in the top rack of the dishwasher. Allowing the parts to dry thoroughly after cleaning improves performance.

Willow Pump - wipe with a damp cloth as needed, never submerge your Pump. No other cleaning is necessary.

Let’s try two solutions involving a battery check and a reset, if these two suggestions don’t help, we will need to gather a bit more information from you. Grab your pump and let’s get started.

Battery and Charging - is your pump connected to the Charger? If so, it will not turn on. Unplug and try to turn your pump on. The power button needs to be held down for 2 - 3 seconds to turn the pump on (this 2 - 3 second hold prevents it from turning on if accidentally bumped in your pumping bag). If the pump will still not turn on, return to charging for 20 min, unplug and try again. Success? Great! If not, let’s reset your pump. 

Reset - follow these simple instructions to reset your pump 

1. 1. Separate your pump from the flange or container.
   2. Gently insert the blunt end of a paper clip or earring back into the tiny hole next to the power port.
   3. Remove the blunt object. You may hear a whirring reboot noise for 2 - 3 seconds and the pump will vibrate softly.
   4. Try turning your Pump on again.

If these steps do not help, complete the form below or give us a call so we can help you.

Additional Troubleshooting Resources to Consider:

The buttons on my pump aren't working, any tips?

My pump won't charge or it won't hold a charge.

We are so sorry that happened to you! 

• Milk leaked into your pump? Leave your pump in a vertical position with the blue pad end at the top and the charging port at the bottom for at least 24 hours without turning it on, charging it, or performing flip to finish. After 24 hours, charge your pump for at least two hours. Check to see that the green light is solid and that your battery icons appear in your app. If so, you’re ready to go! If not, reset your pump.

• Pump making different sounds? If your pump is dropped, exposed to liquid, or stored in the refrigerator, the noise it makes can change. As long as the pump is still pumping and you're getting your milk in the milk bag or container, there's no need to worry about these changes. Resetting your pump may also help.

• Signs of damage or wear and tear on accessories? We recommend you replace accessories every 90 days or immediately if you notice any signs of damage or wear and tear. 

The Willow pump is covered under a 12 month warranty from the purchase date. All accessories - flanges, Flextubes™, containers, and inserts - are covered under a 90 day warranty from purchase date. We will require original proof of purchase if you purchased from an authorized retailer. 

For our complete warranty, please see our current Instructions for Use.

Here are some tips to get you out of this frustrating situation:

Time to transition to expression - are you waiting long enough? Most moms will transition to expression in just over 2 minutes. It can take even longer if you are not expecting a rapid let down (stressful day at work) or recently pumped. Relax, try again and give it 4 - 5 minutes, especially if you are new to Willow.

Alignment - If your nipple is not centered in the tunnel, you may not be expressing milk for Willow to detect. Or your nipple was centered and it may have shifted when you fastened your nursing bra over Willow. Align again and do not fasten your bra until Willow has latched.

Flange size - if Willow is too large or too small, your nipple will not experience the stimulation required for let down. Use our Nipple Sizing Guide to make sure your flange is 2 - 4 mm larger than your measured size.

Additional Resources for Reaching Expression:

My pump isn't moving into expression, any tips?

How do I check if milk is flowing?

I'm unable to adjust suction beyond level 3, any tips?

Willow has three types of buttons (on/off, suction up/down, pump/pause).

Resetting your pump often fixes all 3, let’s start there and reset your pump. If the reset does not work, check for more tips in the correct category below.

Reset - follow these simple instructions to reset your pump 

1. 1. Separate your pump from the flange or container.
   2. Gently insert the blunt end of a paper clip or earring back into the tiny hole next to the power port.
   3. Remove the blunt object. You may hear a whirring reboot noise for 2 - 3 seconds and the pump will vibrate softly.
   4. Try turning your pump on again.

Still having issues? Select the correct category below:

On/Off Button

• • If your pump will not turn on, make sure it’s not connected to the charger.
  • Is your pump charged? If not, charge it and try again. 
  • Are you holding the Power button down long enough? You’ll need to hold it for 1 - 2 seconds to turn the pump on.
  • Are you trying to turn the pump off while you’re pumping? The pump won’t let you do this. Press Pause and break latch, then turn the pump off.

Suction Buttons

• • Do you know your current suction level? Check the app. The down button won't work when you're at Level 1, and the up button won't work when you're at Level 7 (this is Willow's highest suction level). 
  • Suction buttons not responding during stimulation? In stimulation you'll have access to suction levels 1, 2 and 3. Once you have pumped approximately 0.5 ounces of milk you'll have access to all seven levels of suction.

Pump/Pause

• • Willow automatically pauses after 25 minutes of use.
  • Reset is the only fix for this category of buttons, please give us a call if that has not worked for you.

Additional Troubleshooting Resources to Consider:  

What do Willow's buttons do?

Your pumps will only pair to the Willow app compatible with their generation. Check that you have the correct app installed and are using a compatible device. 

Pairing - Make sure your phone’s Bluetooth is On. Then try resetting your pumps and wait 1-2 minutes after tapping “Pair.” Check out our help article on pairing for additional tips.

App reinstall - To pair your pumps again after reinstalling the Willow app, try this.

New phone - For help getting your pumps paired to a new phone, look here.

Unpairing - Go to the Settings tab > Pumps page in the Willow app. Tap “Remove” to unpair your pumps.

Your Pumps are connected when battery icons are displayed in the Willow App.

If one or both battery icons are missing, make sure your phone’s Bluetooth is on, then try the Quick Fixes below or read our help article on getting your pumps to connect.

Quick Fixes - Force close the app, turn your pumps off and back on, reset the pumps, turn your phone off and back on.

Pairing- Check that your pumps are listed in the Settings tab > Pumps page in the Willow app. Your pumps need to be paired in order to connect to the app.

Connectivity - If you can see the battery icons, but they come and go or the suction levels and volume tracking on your home screen doesn’t update while pumping, you likely have a bluetooth connectivity issue. Open your app and connect before pumping and keep your phone nearby.

Does the app work if my phone is in airplane mode?

The Willow pump tracks milk collected in the milk bag or container and the Willow app reports the volume.

It’s normal for the volume reported in the app to differ a little from the actual milk volume you are getting. Most of the time, large app volume inaccuracies are related to the valve on the container or the milk bag. Try a deep clean for your container or a new bag. 

Realigning - If you realign a few times or don't have a good seal, this can impact the accuracy of the volume reported in your app. As you get more experience with Willow and have a good bra, you should see this improve. 

Assembly - A small adjustment to your pump assembly can improve volume accuracy. Review assembly with the container and the milk bag.

Accessories - Wear and tear on accessories impacts volume accuracy. Replace any accessories out of warranty.
