Insurance coverage

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.

Find your fit!

When your pump flange fits properly, you get more comfort, a better latch, and more milk.  To get the most accurate measurement, it’s important to measure your nipples to make sure you have the right size flange or insert for Willow®. 


Willow Go™ - To determine your nipple size we suggest using the sizing tool that came in your Willow Go box.  


Willow 3.0 or earlier - If you are pumping with Willow 3.0 or earlier and need another copy, print this helpful sizing tool. No printer?  There are iOS and Android phone apps that can be useful for measuring as well.  


Willow flanges are available in three sizes; 21mm, 24mm, and 27mm.  Willow sizing inserts fit perfectly in the 24mm flange and are available in sizes 15mm, 17mm, and 19mm.

Boost your volume with Willow®

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 much milk should I expect with Willow Go

We’ve all seen the IG posts with freezers filled to the top with frozen bags of breast milk.  It’s true that some women make more than needed to feed their baby but most make just enough.  Babies from about four weeks of age until 6 months require approximately 24 - 26 ounces in a 24 hour period or about one ounce per hour.  So, if you pumped every three hours ideally you should expect 3 ounces of milk, some moms will get more, some slightly less but on average, that is what we would expect.  


If you are getting less milk than expected, the usual causes are flange sizing, selecting the right bra, and alignment.

Willow®'s alerts and lights

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. 



Open & Close Pump Alertmost 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

Cleaning is simple with Willow®

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.

How do I clean Willow GoTM?  

After every use, you can use the top rack of the dishwasher or wash by hand the five washable parts. Allow your parts to air dry before your next use, you can speed the process by removing the majority of the water with a towel after washing.  The pump itself is not washable. Wipe with a damp cloth as needed.  


Do not use sanitizers, microwave sterilizing bags, or steam sterilizers to clean or sterilize these parts.

Alert messages in the Willow® app

The Willow App sends pumping alerts that correspond to the pump’s lights to help you while you are pumping. See below for a look at the most common alerts and how to resolve them.

 

Open & Close Pump - Click the link to troubleshoot with our interactive helper tool.

 

Flush through Container Valve or Attach Bag - Click the link to troubleshoot with our interactive helper tool.

 

All Full - The pump stops when the container or bag is full. 

 

Bags: If the pump stops sooner than expected, there might be air in your bag. Try these steps to troubleshoot.

 

Containers: Try these steps to ensure the valve is clean and functioning properly.

 

Check Seal - The seal between the pump and the breast was not good enough for the pump to latch. Check for fabric between the pump and your body.

 

The helper tool will walk you through the steps to check for common issues, and gather relevant information to send to Willow Care should you need further support. You can choose to review the steps in troubleshooting videos or go through them step-by-step.

Let's get you back to pumping

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. 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.

Here are some hints to help you figure out what’s going on. 

  • Make sure the pump is not connected to the charger. As a safety measure, the pump will not turn on when connected to the charger.
  • Is your pump charged?  You can check battery status in the app. If it's not charged, charge it and try again.
  • Are you holding the power button down long enough?  You’ll need to hold it for 1 - 2  seconds until pumping begins.

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. Below are troubleshooting steps for a few scenarios our moms have experienced.


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.

 

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

Willow® transitions to expression as soon as the pump detects milk flow.

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.

Reach your optimal output with Willow Go™

Stimulation is a fast-paced suction pattern that stimulates the nipple to bring on milk flow or let down. Expression is a slower and stronger suction pattern. Often best for expressing milk from the breast once milk has begun to flow. 

If you prefer the fast-paced suction - feel free to remain in stimulation for the entire session or switch back to it anytime, play around with all 6 Stimulation suction levels to see which is best for you.  

The pump will start in stimulation mode and automatically switch to expression mode after two minutes of pumping. Press the mode button at any time to change manually. 

If your body reacts better to the slower-paced suction, you’ll want to spend most of your session in expression mode. There are 9 levels of suction to choose from in expression, again, play and see what removes the most milk.

Troubleshooting the pump's onboard controls

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. 

User-added imageReset - follow these simple instructions to reset your pump

Reset - follow these simple instructions to reset your pump

      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.
      5. Still having issues? Select the correct category below:


On/Off Button

      1. If your pump will not turn on, make sure it’s not connected to the charger.
      2. Is your pump charged? If not, charge it and try again. 
      3. Are you holding the Power button down long enough? You’ll need to hold it for 1 - 2 seconds to turn the pump on.
      4. 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

      1. 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).
      2. 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

      1. 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.

Connecting your pumps to the Willow® App

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.

Volume Reporting in the Willow® App

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.

 

 

Additional resources to consider:

If I pump over 4 ounces in a session, can I switch out the container to a bag?

Will the app accurately record my milk volume?

Does the volume displayed in the app include the milk that's in the flange and flextube before flip to finish?

Can I edit my pumping history in the Willow app?
