Are Willow Breast Pumps Worth Your Money?
Willow wearable breast pumps allow you to pump breast milk any time of the day, even when you’re on the go. Many nursing mamas consider them a top baby essential because they offer more mobility and freedom than traditional pumping options.
Yes, it’s true that they’re more expensive than other well-known breast pump brands, for example, Medela and Spectra. Despite the higher price tag, many parents believe that the cordless, hands-free Willow breast pumps are worth the money because they’re more convenient and allow you to go on with your daily life tasks with more ease.
In this Willow breast pump review, we’ll cover all models and key features along with frequently asked questions to help you choose which model is right for you.
How Does The Willow Hands-Free Breast Pump Work?
Many breast pumps have to be plugged into an electrical outlet to work. Others (e.g., portable breast pumps) work with a battery. For most of these breast pumps, you still need to hold the collection base or baby bottles in place while you pump.
While you can use a nursing bra to hold them in place, the dangling bottles are still obvious. Even with battery-operated pumps, you’re unlikely to pump discretely in public.
Hands-free breast pumps like the in-bra, wearable Willow combine the pump with a collection system so you can pump discretely without bottles or containers dangling or protruding from your clothes.
Both Willow 3.0 and Willow Go breast pumps can be connected and controlled remotely through the Willow app. The pumps automatically stop once the containers or breast milk bags (for Willow 3.0) are full.
Is Willow A Hospital Grade Pump?
The brand assures consumers that Willow 3.0 and Willow Go have hospital-grade suction strength comparable to traditional double-electric breast pumps.
Willow 3.0 has up to 245 mmHg maximum suction strength, while Willow Go has up to 280 mmHg.
Like hospital-grade pumps, both have a closed system but are only designed for single, personal use.
Does The Willow Pump Help Increase Milk Supply?
Yes, it can help increase your milk supply. These pumps have a stimulation option and adjustable levels of suction to help encourage milk production.

Useful Tips
How To Find The Best Willow Size
Willow recommends the following size guide in choosing the right flange size for your pump:
- 11-13 mm nipple measurement: 24 mm Willow flange with 15 mm additional sizing insert
- 13-15 mm nipple measurement: 24 mm Willow flange with 17 mm additional sizing insert

- 17-20 mm nipple measurement: 21 mm Willow flange
- 20-23 mm nipple measurement: 24 mm Willow flange
- 23-26 mm nipple measurement: 27 mm Willow flange

Getting Used To A Wearable Pump
You might notice that you aren’t pumping as much as you want to, especially if breastfeeding isn’t fully established yet.
Reading the step-by-step instructions in the breast pump’s user guide is a good idea.
It might take some time before you can get used to a wearable pump. Moms who have tried it recommend continued use until you get the hang of it. Stick with it, mama!
Does It Hurt To Pump Using The Willow?
Willow pumps have suction levels similar to other pumps. Like other pumps, they’re designed to work comfortably.
Nipple cracks and fissures can make pumping (and breastfeeding) painful, particularly during the first few weeks. You can use nipple cream to prevent or ease the pain.
FAQs
Can I Exclusively Pump With Willow?
Yes. Many moms use their Willow to pump exclusively. It’s one of our recommendations for the best breast pumps for everyday use. However, it’s important to consider its battery life.
According to Willow, the batteries can last up to five pumping sessions per charge, but some reviews on Amazon mention that the battery lasts for around two to three pumping sessions (around 20-30 minutes per session).
During the first few weeks postpartum, you might need to pump around 7-8 times daily. This can drain your battery faster.
If you’re going out, it’s a good idea to bring your charger to keep the batteries charged and ready for your next pumping session.
Is It Possible To Use Willow Breast Pumps Anywhere?
Yes, most of the time. Because they’re cordless and wearable, these breast pumps can be used anywhere unless you need to do something that might dislodge them (e.g., strenuous exercise, pilates or yoga, swimming, workout, etc.).
How Long Can You Wear A Willow Breast Pump?
You can wear this breast pump until the containers or milk bags get full (the pump automatically shuts off when these are full).
If you still want to continue pumping, you can replace the milk bag or container.
