If you’re using the 24mm, you might want to try these!!

The hospital gave me 24mm breast shields in my Medela ‘starter pack’. I can’t remember where I got the 27mm breast shields from, but WOW- they seriously make all the difference in the world. You’ll just have to take my word for it that I do NOT have large breasts or large nipples!!My aunt, who is a lactation consultant, said that the 24mm ‘standard’ breast shields actually are too small for most women!I would just recommend that any pumping mom GIVE THESE A TRY!! You might find that you’re able to pump MUCH more milk MUCH faster! And who doesn’t want that?!?

A better fit makes a huge difference

I wish Medela shipped their pumps with the 27mm as well as the 24mm, but I suppose it’s just another way for them to make an extra uck. Luckily in the hospital, a Lactation Consultant had me using the hospital pump and gave me a set of the 27mm. I tried the 24mm when I got home, but they would have never worked – and I probably would have just kept using them as that is what came with my pump and I wouldn’t have realized that a larger size was available. I ordered a second set so I wouldn’t have to keep cleaning them during the day. Give these a try, it made a HUGE difference.

Worth trying-they helped me!

I was cautious to spend money on something I couldn’t try first, but I’m so glad I gave these a shot. The 24mm ones that came with my Pump In Style cause nipple chafing and blanching. These shields are much more comfortable. I haven’t noticed an increase in supply since switching to this larger size, but that wasn’t my goal. This size makes pumping a much more pleasant experience, and anything to make life easier with a newborn is worth trying!

Definitely a good idea

It’s a good idea to consider going up a size. I wasn’t quite sure I needed to go up a size but they’re more comfortable than the ones that come with the pump. I kept trying to find something online that really explained how to know what size you need but didn’t find anything too great. Most don’t seem to say that it’s not just the space you see around the nipple when you put them on, you have to see how much space there is when the pump is on. That’s what matters. The other night I had to use the smaller size and I definitely noticed the difference. It’s worth it to try it. As a side note, I later ordered a pump from Edgepark online and they pump they provided came with a set of the medium flanges and a set of these!

So glad I found these!

After a few weeks of painful pumping I discovered these flanges. I’m so glad I did. In fact, one breast required the larger size while the other is OK with medium. Oh and having spare parts is great when you have a newborn – who has time to constantly wash accessories?!

Much Better

These were much better than the standard size shields for me. I didn’t think that I needed a bigger size until I tried it. Much more comfortable and got more milk this way. I thought you needed as much suction as possible to get the most out, but you can actually not squeeze the life out of yourself and still get what you need!

Medela should include this size

Medela is smart and doesnt include this in their kit. This allows them to sell addons like this make extra money. I feel like this is a common size and shouldve been included in their pump kit.

Fits great

I am not sure if it really helped my pumping capacity and efficiency but i needed a new set since mine were four years plus old. I had the standard size and figured I would try this smaller size. it fit pretty much the same. I think they need an even smaller one.

Medela Horns

These work great.. I needed a larger size and these are just as described. They fit great with my Medela PIS and help with increased milk production as the ones that came with the pump were too small for me. Super fast delivery!

Worth trying a larger size

Consider sizing up to the 27mm from the standard shield if you are getting nipple abrasions around the sides of the areola. These were way more comfortable for me.

These were the perfect size. They were delivered in a good shape. The ones that came with the pump ( 24 mm ) are too small for average women.
