## Description

desertcart.com : One-Piece Breastshield w/Valve, Membrane for Medela Breast Pumps (Pump in Style, Lactina, Symphony), 24 mm Standard breastshields; Replacement of Medela PersonalFit Breastshield (Medium 24 mm, : Breast Feeding Pumps : Baby

Review: Finally a fit, and a Quality Made Product - First of all, I just want to say, the product (Maymom made 21mm one-piece breastshield) is quality made, and I have been using it for the past three weeks. No more pains! Ya. I expressed at least 1 oz more milk every session after I have used these 21 mm breastshields. This one piece product works as well as the two piece Medela PersonalFit 21mm one. What I would like to share more is how I came to this product. Like everyone else, I tried the 24 mm breastshield that came with the machine. As a first-time mother, I thought having some pains after a pumping session is normal. I was wrong. After few days of using it, the pains were terrible. I experienced a lot of pains and bruising from using the standard 24mm shields. From the diagrams on Medela's website and the information that comes with the pump, the flange should fit with just your nipple being pulled in during pumping. It is confusing if you have a mixed areola/nipple area. The problem is that my 'areola' protrudes about 1/8 inches and I thought that is part of the 'nipple' area when I talked to a lactation consultant. The lactation consultant told me to try larger breastshields. I tried larger one (27 mm), though it did not hurt as much, my milk supply went down by one-third and the bruise area became large. I felt every suction along the pumping. I tried the next size up - 30 mm, even worse! After reading more and more reviews, I decided to try a smaller one. I ordered both Medela's PersonalFit 21 mm breastshield and this Maymom made one (it is cheaper, and others said it is easier to clean). Tada.. No more pains. Both brands worked well. Finally a FIT. I realized now that when I was using the larger ones (27 mm and 30 mm), it was more of the 'areola' that was pulled into the tunnel and the milk ducts were blocked during a suction action. Therefore, less milk supply. When I was using the medium one, the sensitive area of my 'areola' was rubbing the tunnel, thus pains. So the bottom line - know what are the nipple and areola of your breasts. It is the nipple part that should go into the breastshield tunnels, not the areola. Choose the right size and pumping will no longer be painful!
Review: Highly recommend! Fits madela Instyle pump parts perfectly - This should be the standard issued size with your pump! there is little to no info given on breast shield sizes when your starting your journey to breastfeeding and pumping, and having this little piece of info can be a game changer! I was issued my Madela Instyle Advance pump with 24cm shields, and they were so large I had my whole( small b cup) boob basically squeezing into that thing and losing suction the whole time, having to hold them on to pump anything at all, all the while not knowing any better that it shouldn't be like that, you shouldn't have that much in there, and you shouldn't be in pain. This made ALL THE DIFFERENCE! I actually have milk pumping properly and in abundant amounts, I'm not in pain, and not having to hold onto them the whole time, which was the huge thing. Ladies, if you have small breasts, see if you have the right size shield. Also try a pumping bra that's not the strapless zipper one from madela. I bought the hofish brand two pack for $25 here on desertcart and it also made a huge difference! I wasn't constantly pulling it up because of my small chest making the strapless madela one roll downward. They are optional strapless too, but adjustable in the back so it isn't a crappy zipper that breaks every month or so. purchasing these shields changed my entire perspective on pumping and my whole experience with nursing too. I increased my breastmilk supply having been able to pump properly when needed, and express what I needed when baby was done nursing. Seriously look at the shield size chart from madela, I never knew it existed until I saw these online and looking on Pinterest I found the chart.

### ⭐⭐⭐⭐⭐ superior to the medela flanges, size is perfect for me
*by D***M on September 28, 2014*

I have been using the standard medley pump flanges for a few years with my first son and now with my second. I used to get bruises and have lots of pain when I used these... I didn't know the flanges came in other sizes. I know I have very small nipples and I didn't realize that the pump was actually taking in tissue it wasn't supposed to suck in. I honestly just thought to look into alternative pump flanges a month after my second son was born and I did it because the end of the areola and nipple never felt drained, when I self expressed, I always got another let down and it was back on with the pump flange. So I decided to get the smallest flange out there and I am so glad I did! these 19mm openings produce more let downs, my nipples aren't misshapen afterward and they no longer bruise or hurt. I think the design is similar but improved upon the original flanges in a way that minimizes spray in the vertical chamber which reduces waste...for those of us who try to recover every last drop. The perfect way the milk falls from its intended port into the second chamber is so much more direct and as the design has intended it compared to the other flanges. I don't like 2 things, the opacity of the thicker plastic nipple chamber makes visibility difficult. I use compressions in conjunction with each let down and in between them so I do watch for visual confirmation in the chamber. However, the thickness of the chamber surrounding plastic is an improvement over the other flanges...I actually have a crack in one of the first flanges I used in the chamber which could have soon spread and compromised its suction. The overall construction of these flanges is superior and improved. Everything fits very snugly where parts are meant to be attached. The second thing I don't like is that these flanges are smaller and aren't as secure in my hands free pumping bra with round holes (not the type with overlapping material) as the larger, original flanges...the holes in the bra are somewhat stretched and if I compress during pumping, the bottom of the flanges can pop out of the hole. This too has an upside...i am able to compress more breast tissue without the larger perimeter of the other flanges...so I can just get another bra or modify this one. And, the diameter, of course, is perfect for me. I think this company has made a superior product both in design and function...they offer a size medley does not and it's exactly what I needed. It's a well priced product...they seem well worth the price and I would have paid more for these after knowing what I know about them now. I highly recommend trying a smaller flange if you experience bruising or have build up of milk in your nipple that isn't adequately removed while pumping.
