How to choose the right breast pump and flange size: A guide for you

Dear Mum, if you are reading this article, you are probably trying to figure out which breast pump is best suited to your needs. Not all breast pumps are the same, and what works for another mother may not be the right solution for you. There are many options, from manual to electric, single or double, and even hospital grade breast pumps. Each one has features that make it more or less suitable for different situations, such as how often you need to extract milk or why you do it.

But there is one aspect that is little talked about and that can really make a difference in your experience: the size of the flange. This small detail is crucial to ensure your comfort, efficiency and even to prevent pain or irritation. The wrong size flange can compromise everything, making extraction a frustrating and less productive experience.

In this guide, I will help you navigate your choice of breast pump and, more importantly, understand how to find the perfect flange size for you, so that you can enjoy this phase with confidence and success.

Manual vs. electric breast pump: which one to choose?

Manual breast pump: The manual breast pump is simpler and cheaper. It works by hand power, so it is ideal if you need to pump occasionally or when you are away from home and don’t have access to an electrical outlet (although many electric ones now have a battery). It is lightweight and portable, but requires more time and effort than an electric model.

Electric breast pump: The electric breast pump is an ideal choice if you need to pump regularly, for example if you are going back to work or need to stimulate milk production. It works automatically and can be adjusted for speed and extraction force. It is faster and less tiring than manual, but usually bulkier and more expensive. Some models have a double extraction function, which allows milk to be pumped from both breasts at the same time, reducing the overall extraction time.

Wearable breast pumps: This model of breast pump is a novelty in recent years, designed for when you are short of time and want to have your hands-free during use. Beware, however, because not all models on the market are as effective as the classic electric ones; in addition, many have a shape and opacity of the flange that does not allow you to see the nipple during extraction, which is essential to better understand if the size is right for you and thus not compromise efficiency.

Single vs. double breast pump: which option is best?

Single breast pump: The single breast pump is a good choice if you need to pump milk from one breast at a time. It is more compact, easy to use and generally cheaper than the double. If you have no special needs or if you have time on your hands, a single model may be sufficient.

Double breast pump: The double breast pump allows you to pump milk from both breasts at the same time, which can reduce the pumping time and increase milk production, as it stimulates both breasts at the same time. This option is ideal if you have to pump frequently and need to increase milk production, especially when your baby is not latching on to your breast. Although it is more expensive than the single breast pump, the possibility of saving time can be a great advantage.

Hospital grade breast pumps: what does it mean?

The term hospital grade refers to a type of breast pump that is designed for professional use, often in healthcare facilities. These models are particularly powerful, efficient and able to extract milk more quickly and effectively. They are suitable if you have special needs, such as if you have your baby in hospital or if you have a low milk supply and need to express milk very frequently. Usually, hospital grade breast pumps are rented from pharmacies or health shops (they are very expensive so cannot be bought) and bulky, but they are known for their durability and reliability.

Flange size: why is it so important?

One of the most important things to consider when choosing a breast pump is the size of the flange, the part that fits over the breast. A flange that does not fit correctly can cause pain, irritation and low output during extraction. The right flange must be the right size for your nipple so that extraction is comfortable and effective.

How to choose a flange size?

Flanges come in different sizes. The most common size that is sold is 24 mm, but it is important to know that every breast is different, and, to be honest, size 24 is large for most mums! The flange should fit comfortably around your nipple, without causing discomfort or pinching. If the nipple is pulled excessively so that it also pulls part of the areola, or if it touches the edges of the flange, you may have to choose a different size.

There are tests to determine the right size: you can try measuring the diameter of your nipple (not including the areola) or ask a midwife or lactation consultant for advice, who can help you find the right flange for your body. Usually the right size for you is 2-3 mm larger than your nipple diameter (e.g. if your nipple size is 18 mm the right size for you is 21 mm).

Common flange sizes are: 21 mm, 24 mm, 27 mm, 30 mm but remember every breast is different and you may need smaller sizes too!

If the flange is too big or too small, it may not pump the milk properly, or it may cause pain and insufficient production. Some breast pumps offer interchangeable flanges, allowing you to easily change the size if needed. Most commercial breast pumps offer little choice of flange size; if you have a nipple size of 17mm or smaller, I recommend that you seek support from a lactation professional to understand which flange to take.

Other factors to consider

In addition to the type of breast pump and the size of the flange, there are other aspects to consider:

• Noise: If you plan to use the breast pump at night or in a quiet environment, choose a quiet model.
• Ease of cleaning: A breast pump that is easy to disassemble and clean will save you time and maintain maximum hygiene.
• Portability: If you travel a lot or have limited space, you may prefer a more compact and lightweight breast pump.
• Don’t share: Most breast pumps are not meant to be shared by multiple users for hygiene reasons (yes even if sterilised!). If you want to know more about this or how to use a breast pump click here.

Concluding

Choosing the right breast pump depends on your specific needs. If you plan to pump milk occasionally, a manual or single model might be sufficient. If you need to pump frequently, consider an electric or double model. Don’t forget to also choose the right flange to ensure maximum comfort and efficiency.

Take your time to make the right choice and don’t hesitate to seek advice from a lactation consultant if you are unsure. Every mother is unique, and finding the perfect breast pump for you can make a big difference in your breastfeeding experience.
