Breast Pump Flange Sizes: Why They Matter and How to Choose the Right One

The selection of the flange size is among the main steps to successful and comfortable pumping, particularly among mums who have to use the electric breastfeeding pumps. 

Lots of new mothers are unaware that the funnel-shaped object that goes on top of the nipple, the flange, contributes significantly to the amount of milk they can produce and the comfort of each session.

A wrong flange size may result in pain, inefficient suction, low output of milk and even damage to the nipple. But the good news? When you understand what to look at, then it is not hard to select the right size.

So in this blog we are going to dissect why flange size is important, how to measure yourself, and how to find the most suitable one for your body. Whether you're a new mum or an old pumper, this guide will assist you in pumping more comfortably and efficiently.

Why Does Flange Size Matter?

1. Comfort During Pumping

The size of the right flange must assist your nipple to swing freely within the tunnel without scratching the walls. In case the flange is not wide enough, your nipple can grind, which is painful, reddish, or swollen. When it is too large, too much of the areola is pulled into it, and this becomes uncomfortable and inefficient to pump. Due to the higher speed and suction rate of electric breastfeeding pumps over manual ones, the fit is quite important as well.

2. Better Milk Output

A properly fitted flange assists in the formation of a good steady vacuum. This implies that there is increased milk in the shortest time. A wrong flange size can result in a poor suction or air leakage that does not allow the pump to perform properly. A lot of mums can discover that the only thing that raises their milk production is a bigger flange.

3. Prevention of Nipple Damage

The improper flange size may result in broken nipples, bruising, erythema and pain. Specific problems like obstructed ducts or mastitis may develop in the long term. You have the right size, your breast tissue is protected, and the pumping process becomes a lot easier.

4. Enhanced Pumping Performance

With the flange properly installed, your electric breastfeeding pump will be able to perform to its capacity. This will allow you to complete sessions at a quicker rate, eliminating you from the long and painful pumping practices and relieving your daily schedule, particularly when you are a working mum.

Selecting the Right Flange for Your Electric Breastfeeding Pump

1. Know Your Pump Brand

There is a system of size in each brand of pumps. Others have standard sizes, such as 24 mm or 27 mm, or are more customised, such as 17 mm or 19 mm. See the size chart of your particular pump model.

2. Consider Silicone Cushions

Rigid plastic flanges have been reported by some mums as uncomfortable. Silicone flanges or cushions may be nicer on the skin and offer a more effective seal, particularly on mums with sensitive nipples.

3. Look for Adjustable Flanges

Adjustable sizes of flange or inserts are now available in some modern electric breastfeeding pumps. This comes in handy when the size of your nipples varies with time or when you pump very often.

4. Don’t Ignore Comfort

Although a size may look right when measured, comfort is what to rely on in the end. In case of discomfort or low output of milk, use another size.

5. Track Your Milk Flow

The right flange size would contribute to let-down stimulation and constant milk flow. When pumping is time-consuming or the production of milk reduces, the size of the flange can be a consideration.

Helpful Tips for Better Pumping

• Apply a small amount of nipple balm before pumping to reduce friction.

• Make sure the pump suction is not set too high.

• Take short breaks during long pumping sessions.

• Massage your breasts before and during pumping to stimulate milk flow.

• Recheck your flange size every few months.

These simple steps can improve comfort and output, especially if you use electric breastfeeding pumps daily.

Final Thoughts

The correct flange size might be a minor detail, but it makes a massive difference to your pumping experience. The correct size will keep you comfortable, keep your nipples healthy, maximise your milk output, and make your pump effective. Every mum has a different body, and it can be much easier and more enjoyable to pump after spending a couple of minutes measuring and testing the body.
