Customer Questions & Answers
-
Question:
What is the Willow Flange Sizing Kit?
Answer: The Willow Flange Sizing Kit is a specially designed kit for optimizing breast pump flanges. It includes several inserts (13mm, 15mm, 17mm, 19mm, and 21mm) to ensure a proper fit with most 24mm flanges on the Willow Go and Wave breast pumps. A proper flange size is crucial for effective pumping, as it can significantly enhance comfort and milk output. This kit provides flexibility to find the best size tailored to your body, ensuring an efficient breastfeeding experience. -
Question:
How do I know what size flange I need?
Answer: To determine your flange size, start by measuring your nipple diameter while your breast is not stimulated. This will guide you to select the appropriate insert size from the kit. It's important to choose a size that allows for a snug fit without pinching or discomfort. An accurate flange size maximizes milk flow and comfort, allowing breastfeeding mothers to pump more effectively, which is crucial in postpartum recovery and maintaining milk supply. -
Question:
Can I use the Willow Flange Sizing Kit with other pumps?
Answer: Yes, while the Willow Flange Sizing Kit is designed for use with Willow Go and Wave pumps, it can be compatible with other breast pumps that utilize 24mm flanges. Be sure to check your pump's specifications. Using the sizing inserts can help you achieve optimal comfort and efficiency with any compatible pump, making it a versatile addition to your breastfeeding essentials. -
Question:
Is the sizing kit suitable for all breast sizes?
Answer: Yes, the Willow Flange Sizing Kit accommodates a range of breast sizes, offering inserts in various dimensions to help mothers find their perfect fit. This customization is essential since breast anatomy varies significantly among women. Whether you're small or large-breasted, having options means you can ensure that your pump operates efficiently and comfortably, enhancing your breastfeeding journey. -
Question:
How should I clean the Willow Flange Sizing Kit?
Answer: To maintain hygiene, each insert in the Willow Flange Sizing Kit should be washed with warm soapy water after each use. Rinse thoroughly and allow to air dry before storing. This not only ensures cleanliness but also preserves the longevity of the inserts. Adopting such care practices contributes to a healthier breastfeeding routine, which is paramount in the early weeks postpartum. -
Question:
Can I adjust the inserts once they're in the flange?
Answer: Once the inserts are securely placed in the flange, they are not intended to be adjusted during pumping. It is recommended to select the desired insert size before starting your pumping session. This ensures a proper and consistent fit throughout your session, facilitating effective pumping and maximizing comfort for the best results. -
Question:
What are the benefits of using the Willow Flange Sizing Kit?
Answer: The primary benefits of the Willow Flange Sizing Kit include personalized comfort, improved milk output, and reduced risk of pain or injury during pumping. By finding the right insert size, mothers can enhance their pumping experience, allowing for a smoother breastfeeding process. The result is increased satisfaction, as well as maintaining a healthy milk supply when combined with regular breastfeeding or pumping. -
Question:
How do I store the inserts when not in use?
Answer: To store the inserts when they are not in use, it is best to place them in a clean, dry container to protect them from contaminants. Keeping them in a dedicated spot prevents loss and maintains organization. Good storage practices contribute to a seamless pumping routine, allowing you to quickly access the inserts when needed for effective breastfeeding sessions. -
Question:
Are there any specific care instructions for the inserts?
Answer: In addition to regular cleaning, avoid using abrasive materials when washing the inserts, as this may damage the surface over time. It's advised to inspect the inserts for any signs of wear or damage before each use. Taking these precautions ensures that the inserts remain effective and safe for your pumping sessions, contributing to your overall breastfeeding experience. -
Question:
Where can I buy the Willow Flange Sizing Kit?
Answer: You can purchase the Willow Flange Sizing Kit from Ubuy in Saint Lucia. Ubuy offers a convenient platform with a variety of breastfeeding essentials, including the sizing kit, making it easy for new mothers to find the products they need for their postpartum journey.
