Learn the benefits of double pumping with the Willow Go® wearable pump, plus step-by-step tips for maximizing milk output and comfort.

If you're a busy mom, you know that time is precious. Every minute spent pumping is a minute away from your baby, your work, or your own self-care. That's why double pumping—pumping both breasts at the same time—is a game-changer. Not only does it cut your pumping time in half, but research suggests it can also increase milk production and lead to a higher overall milk yield.

The Willow Go® wearable pump is designed to make double pumping effortless. Its discreet, hands-free design lets you pump both breasts simultaneously while you go about your day. Whether you're at work, on the go, or just need some time to yourself, the Willow Go® allows you to pump efficiently and comfortably. In this guide, we'll walk you through everything you need to know about double pumping with the Willow Go®, from setup to maximizing your output.

Why Double Pump with Willow Go®?

Double pumping is not just about saving time—it's also about maximizing your milk supply. When you pump both breasts at the same time, your body releases more prolactin, the hormone responsible for milk production. This can lead to a higher overall milk yield compared to pumping one side at a time. Additionally, double pumping helps maintain a consistent milk supply and can prevent issues like engorgement or mastitis.

The Willow Go® is specifically designed for double pumping. Its wearable, hands-free design means you can pump both breasts without being tethered to a wall outlet or holding flanges in place. This allows you to move freely, whether you're working at your desk, doing household chores, or even taking a short walk. With the Willow Go®, you can truly multitask while ensuring your baby gets the best nutrition.

  • Saves time by pumping both sides at once
  • May increase milk production due to higher prolactin release
  • Hands-free design lets you move and multitask
  • Discreet and quiet, perfect for public or office use

Step-by-Step Guide to Double Pumping with Willow Go®

Getting started with double pumping is simple. First, ensure your Willow Go® pumps are fully charged and that you have clean, properly fitted flanges. If you're unsure about your flange size, check out our guide on choosing the right flange size. Next, place the pumps inside your nursing bra, making sure the flanges are centered over your nipples. The Willow Go® is designed to fit securely in most nursing bras, but you may want to wear a hands-free pumping bra for extra support.

Once the pumps are in place, press the power button on each pump to start. You can adjust the suction and speed settings to your comfort level. Many moms find that starting with a lower suction and gradually increasing it helps with let-down. The Willow Go® offers a two-phase pumping system that mimics a baby's natural sucking pattern, which can help stimulate milk flow. Pump for about 15-20 minutes or until your breasts feel empty.

After pumping, carefully remove the pumps and pour the milk into storage bags or bottles. The Willow Go® is compatible with Willow 360® Spill-proof Milk Bags, which are designed to prevent leaks and make storage easy. You can also use the Willow 360® Pump and Container Bundle for a seamless transition from pumping to storing.

Tips for Maximizing Milk Output While Double Pumping

To get the most out of your double pumping sessions, consider these expert tips. First, try to pump at the same times each day to establish a routine. Your body thrives on consistency, and regular pumping can help maintain your milk supply. Second, stay hydrated and eat a balanced diet. Milk production requires energy and fluids, so make sure you're taking care of yourself.

Another tip is to use breast compressions during pumping. Gently massaging your breasts while the pump is running can help empty them more thoroughly and stimulate additional milk release. You can also use the Hot & Cold Breast Therapy Packs before or after pumping to help with let-down or to soothe sore breasts. These packs are a great addition to your pumping routine, especially in the early weeks.

Finally, don't forget to replace pump parts regularly. Over time, diaphragms and valves can wear out, reducing suction efficiency. The Willow Go® Pump Diaphragm Set and Willow Wave Valves Set are designed to keep your pump performing at its best. Regularly checking and replacing these parts ensures you're getting optimal suction and maximum milk output.

  • Stick to a consistent pumping schedule
  • Stay hydrated and eat a healthy diet
  • Use breast compressions to aid milk flow
  • Consider using therapy packs for comfort
  • Replace pump parts like diaphragms and valves regularly

Troubleshooting Common Double Pumping Issues

Even with the best pump, you may encounter occasional issues. One common problem is one breast producing less milk than the other. This is normal—most women have a 'slacker' side. To address this, you can pump the lower-producing side for a few extra minutes or use breast compressions on that side to encourage more milk flow.

Another issue is discomfort or soreness. If you experience pain while pumping, check your flange size and ensure the suction is not too high. The Willow Go® allows you to adjust the settings to your comfort. If you continue to have discomfort, consider using the Breastfeeding Care Kit, which includes soothing creams and nipple shields to help prevent and treat soreness.

If you notice a decrease in suction or milk output, it may be time to replace your pump parts. The Willow Go® Pump Diaphragm Set and Willow Wave Valves Set are easy to install and can significantly improve performance. Regular maintenance is key to ensuring your pump works efficiently for months to come.

  • Uneven milk production is normal; pump the lower side a bit longer
  • Adjust suction and flange size for comfort
  • Use nipple care products if soreness occurs
  • Replace diaphragms and valves regularly to maintain suction

Double Pumping on the Go: Travel Tips

One of the biggest advantages of the Willow Go® is its portability. You can double pump anywhere, whether you're traveling by car, plane, or train. To make on-the-go pumping even easier, consider investing in the Travel Cleaning Pack. This compact kit includes everything you need to clean your pump parts without access to a sink, making it perfect for travel.

When traveling, it's also important to keep your pump charged. The Willow Go® Dual Port USB Charger allows you to charge both pumps simultaneously, so you'll never be stuck with a dead battery. Pack this charger in your diaper bag or carry-on to ensure you can pump whenever and wherever you need to.

Finally, think about milk storage. The Willow 360® Spill-proof Milk Bags are ideal for travel because they're leak-proof and lie flat, making them easy to pack. You can also use the Breast Milk Bag Flatteners to save space in your cooler or freezer. With the right accessories, double pumping on the go is a breeze.

  • Use a travel cleaning kit for on-the-go sanitation
  • Keep both pumps charged with a dual USB charger
  • Opt for spill-proof storage bags for travel
  • Use bag flatteners to save space

Double pumping with the Willow Go® is a smart choice for any breastfeeding mom. It saves time, boosts milk production, and offers the freedom to move while pumping.
