The history of the 24mm pump flange is closely linked to the evolution of breast pump technology. Breast pumps have been around for over a century, but significant advancements began in the 20th century. Early breast pumps were manual, cumbersome, and often inefficient.
In the mid-20th century, electric breast pumps were introduced, revolutionizing breastfeeding by making it easier and more efficient to express milk. However, these early models were still quite rudimentary in design.
The 1980s and 1990s saw significant improvements in breast pump technology, with companies like Medela and Ameda leading the way. During this period, a range of flange sizes was developed to accommodate different nipple and breast sizes. The 24mm flange size became a standard option, as it was thought to fit a significant portion of women effectively. However, over time, it has become evident that the 24mm size is often too large for many women. Research and user feedback have shown that the majority of women actually require smaller flange sizes for a proper fit and comfort.
The predominance of the 24mm flange as a default size reflects an initial lack of understanding and support for the anatomical diversity among breastfeeding mothers. Many women experience discomfort and inefficient milk expression due to using flanges that are too large. This mismatch can lead to reduced milk supply and a negative breastfeeding experience.
Today, there is a growing awareness of the need for a wider variety of flange sizes that truly support the diverse needs of breastfeeding mothers. Companies are increasingly offering smaller flange sizes and more customizable options to ensure a proper fit for all users. This shift towards inclusivity and better support for all anatomical variations marks a significant improvement in the breast pump industry, aiming to enhance the breastfeeding experience through better technology and design.
Colostrum is thick and sticky. Pumps are great for stimulating milk but they’re not the best at removing it from the breast and it can be very frustrating to pump and not see anything filling the bottles. Don’t be discouraged. Stimulation is super important in the early days after birth and the work will pay off. hand expression is the key to emptying colostrum when pumping. The pump will do a good job to stimulate your hormones to make milk and your hands will help empty it.
If you’re engorged or have an oversupply, you may need to pump to relieve the pressure in your breasts. Using the pump wisely can reduce your engorgment while not causing you to make too much milk and perpetuate your problem.
You can also pump to increase milk supply by pumping for an extra 5 minutes after milk stops flowing to signal to your body that it needs to produce more milk. If you’re breastfeeding and pumping after, aim for a 10-15 minute pump. If you’re exclusively pumping, shoot for a 30 minute pump.
Whether you’re pumping at work to maintain supply or trying to increase your supply, using the settings on the Spectra can help you reach your goals. Have you played around with your settings? What works for one person may not work for another. Try alternating back and forth between the settings and play around with the suction and cycle levels. If you need to have the suction cranked to the top, you’re most likely using too large of a flange.
Everyone responds differently to pumps. Play around the settings and cycles. What works for one person may not work for every person. Make sure your suction level is comfortable and you’re using the correct sized flange. If you have to crank the suction all the way up, you’re pumping with a flange that’s too large. Pumping should be comfortable. You should not have pain or damage from pumping. If you have any pain or damage, try a different range size, shape or cushion and try lowering the suction. If you’ve been pumping on a particular set of settings and start to notice a decrease in supply or suction, change the soft pieces of the pump like the duckbill or membranes and the tubing.
Pumps are machines designed to help establish and maintain milk supply to feed your baby. They are not perfect and no where near as efficient as a baby If they are not used correctly they can fail you (and your supply). Make sure you’re using the correct sized flange and alternating between the settings. Pumps don’t measure milk supply. They also don’t measure your worth as a parent. If your milk supply dropped because of the pump, the pump failed you. You are not a failure.
Pumps are a modern invention and are far from perfect. They’re still seem like rotary telephone technology in an iPhone generation. The first pump was patented in 1854, and the second patent in 1864 was literally for cows. New pumps were created every few years, typically as improved medical devices used to treat inverted nipples and to help babies who were too small or too weak to nurse, but comfort was not the priority. Widely available products for personal or home use have really only been around for about 30 years. It wasn’t until 1991 (around the time most of y’all who are reading this were born) that the Swiss manufacturer Medela introduced its first electric-powered, vacuum-operated breast pump in the US for personal use. Prior to that pumps were limited to select hospitals. Pumps have become such a common tool that many of us think you have to pump if you want to be successful at breastfeeding. While pumping may be needed for some to help establish and maintain supply or for when away from baby, if all is going well and you’re with your baby there’s never a need to pump.
What pump do you have? What size flange are you using? The answer can make a huge difference in pumping success.
Not all pumps are created equal. Prior to the ACA, there were few pump choices. Once laws said people needed to be provided with a breast pump, and insurance would fit the bill, lots of companies flooded the market with pumps. Not all of them are good, and some will even sabotage your supply. You want a pump with a good motor in it that has lots of variability in the cycle (how fast or slow it pumps) and suction (how strong it sucks).
You also need to be mindful of the flange you’re pumping on. Most companies will send a standard 24mm flange. Sometimes they’ll send a larger size as well. In reality nipples, and thus flanges, are not one size fits all. And in my practice I hardly EVER use the 24 or bigger flanges. For almost all of my families we’re sizing down. Some times significantly smaller.
Flanges are the horn shaped part that actually touch the breast. The fit of the flange can make or break your pumping experience. Too small and friction can cause pain and even damage (and pain makes it difficult for milk to let down). Too large and the breast may not be stimulated well, which inhibits your let down to have milk flow. When too much areola is pulled into the flange, the tissue swells around the nipple pores and can prevent milk from efficiently emptying from the breast, resulting in plugged ducts, pain, tissue breakdown, and eventually a reduced milk supply. Using too large of a flange from the beginning may even prevent you from bringing in a full milk supply. Do you ever pump for 20+ minutes and still feel like there’s milk in there? Most likely too large of a flange. The stimulation from the pump is triggering you to make more milk, but the size of the flange is preventing you from emptying that milk efficiently. Poor flange fit can also impact the suction of your pump and how well it functions with your body. If you have the suction all the way to the highest level and aren’t emptying well, you flange is too big.
Flange fit tips:
Some of the flanges I tried
🗝Flange fit isn’t based on your breast or areola size, it is JUST the size of the nipple and how it changes with suction. Some nipples are dense and don’t stretch much. Some are super elastic and swell a lot. How your nipple responds to suction can make a difference in which flange you select and if other products are needed to happy pump
🗝Proper fit isn’t as simple as measuring your nipple, but it’s a start. See a trained IBCLC to help if you haven’t found the right fit or are struggling with poor output, pain/damage, or plugged ducts
🗝A small amount of space around your nipple in the flange tunnel is good. There should be no space around the areola or in the larger bell part of the flange. If your breast tissue recoils back into the horn part of the flange with every cycle, the flange is too large. If the tissue is white where the tunnel meets the horn, the flange is too small
🗝Pain or blanching means it’s the wrong size
🗝Nipples rubbing against the sides of the flange tunnel mean fit needs to be improved and there is a risk of pain and damage
🗝There should only be a small amount of areola pulled in the flange tunnel space. The bell or horn part will have most of the areola held back so it doesn’t get pulled into the tunnel
🗝The nipple tip shouldn’t hit the back of the flange. This means you have an elastic nipple. Sizing up isn’t necessarily the right answer. Using a pump insert, cushion like @beaugenmom or @pumpinpalofficial may be a better solution
🗝Evaluate as you pump. You can changing flange size mid-pump to improve comfort if you’re between sizes. You may also need to change the flange size the longer you pump. Our nipples can become more elastic and larger or smaller with time.
🗝Every nipple is unique and each side may use a different size (or shape/brand!). There are all kinds of flange sizes, inserts, and cushions to improve the pump experience
