Why I Believe a 21 Mm Breast Shield Medela is Necessary
As a new mother, I quickly learned that breastfeeding is not always as simple as it seems. One of the challenges I faced was finding the right breast shield size for my pumping sessions. That’s when I discovered the 21 mm breast shield by Medela, and it has made all the difference in my breastfeeding journey. Here are a few reasons why I believe this particular size is necessary.
Firstly, using a correctly sized breast shield can make pumping more comfortable and efficient. When the shield is too small or too big, it can cause discomfort and even pain during pumping. With a 21 mm breast shield, I have noticed that my milk flows more easily and my nipples are not as sore after each session.
Secondly, using a 21 mm breast shield can help maintain milk supply. A properly fitting breast shield allows for better milk removal from the breasts, which signals to our bodies to produce more milk. This is especially important for mothers who may be struggling with low milk supply or trying to increase their supply.
Lastly, a 21 mm breast shield is essential for mothers with smaller nipples or those who have had difficulty latching their baby onto the breast. The
My Buying Guide on ’21 Mm Breast Shield Medela’

After trying out multiple brands and sizes, I found that the 21 mm Breast Shield Medela was the perfect fit for me. In this buying guide, I will share my personal experience and provide you with all the necessary information you need to make an informed decision on purchasing the 21 mm Breast Shield Medela.
What is a Breast Shield?
A breast shield is a cone-shaped device that fits over your nipple and areola during pumping. It creates a seal around your breast to help draw out milk from your breasts more efficiently.
Why Choose Medela?
Medela is a well-known and trusted brand in the world of breastfeeding and pumping. They are known for their high-quality products and have been providing moms with innovative solutions for over 60 years. With their focus on research and development, Medela continues to be a top choice for breastfeeding moms.
Why 21 mm Size?
The size of your breast shield is crucial in ensuring comfort and efficiency during pumping. The 21 mm size is considered small/medium and is suitable for most women with average nipple size (around 17-20 mm). It is also recommended by lactation consultants for moms who have issues with milk flow or latching.
How to Determine Your Size?
Medela offers various sizes of breast shields ranging from 21 mm to 36 mm. To determine your size, measure the diameter of your nipple at its base (where it meets your areola) using a ruler or measuring tape. You can also seek guidance from lactation consultants or use Medela’s online sizing tool.
Benefits of Using 21 mm Breast Shield Medela
- Fits Comfortably: The soft silicone material and proper fit make pumping more comfortable compared to other brands.
- Promotes Efficient Milk Flow: The unique shape of the breast shield stimulates multiple milk ducts, resulting in more efficient milk flow.
- Easily Compatible: The 21 mm size is compatible with all Medela pumps, making it easy to switch between different pumps if needed.
- Durable Material: Made with high-quality BPA-free silicone, this breast shield can withstand frequent use without losing its shape.
Things to Consider Before Purchasing
- Nipple Sensitivity:The smaller the size of the breast shield, the higher chances of sensitivity or discomfort. If you have sensitive nipples, you may want to consider sizing up.
- Milk Supply:If you have an oversupply or larger breasts, you may need a larger sized breast shield for efficient pumping.
- Pump Compatibility:If you plan on using a pump other than Medela brand, make sure they are compatible before purchasing.
In Conclusion
The right sized breast shield can make all the difference in your pumping experience as a breastfeeding mom. After trying out different sizes myself, I found that the 21 mm Breast Shield Medela was perfect for me. It provided comfort and efficiency without compromising on quality. I hope this buying guide has helped answer any questions you may have had about purchasing this product!
