"Throughout my 1yr+ pumping journey I changed insert sizes 3 times! I love that these are flush with the flange. Sometimes unexpectedly you need to change your size and this helps you determine a good fit by trying at least 2 or 3 sizes to get the best comfort and output! Will definitely ease the stress of waiting days for a new size to come in the mail; if you already have this at home in your pump toolkit!"
"Packaging was great and secured. The kit is amazing and has everything you need, from the measuring tool to different sizes of inserts. This is perfect especially for us moms who use different sizes. And not to mention when size changes during our breastfeeding journey. The inserts are longer than my current ones which is great (prevents the pinching I have with my current inserts) and are super soft. The perfect complement to the willow pumps."
"I didn't realize I was using the wrong size flange until I used this sizing kit. After measuring and using the correct insert, I almost doubled my output! The material of these inserts is super soft and comfortable to pump with, and I can finally use my Willow Gos more regularly."
"Where was this 15 yrs ago when I was a new mom. After discovering Willow 3 yrs ago this new size box is perfect for any pump and any nursing mama! This is so easy to determine proper sizing. It works well considering all you need for that perfect size is all in 1 box! I highly recommend to anyone starting their breast feeding/pumping journey!"
"These are great for those like myself who are sized outside the standard 24 that pretty much every pump comes with. They fit perfectly inside the standard 24 flange I was using. They're easy to clean and I felt like it stimulated milk production more. The only downside is I would only be using the 21 inserts and not any of the smaller sizes offered. I probably wouldn't use the free consultation with a willow sizing specialist but it's a great added bonus for those wanting to utilize it!"
"I'm 7 months into pumping, and this sizing kit is easily the nicest one I've tried. The sizing tool and tips ended up with me getting a more accurate measurement and different flange insert size than when I had sized with a different kit, and my output has increased since switching to these! The flange inserts themselves feel so much higher quality and are much more comfortable- they don't feel pinchy at all. I would absolutely recommend this kit to anyone new or deep into their pumping journey!"
"This sailing kit came with all the bells and whistles compared to others! Not only did I get the traditional paper sizing cut out but also flanges to trial. The kit included a 1:1 consult with a specialist which I thought was amazing! I now have my correct flange sizes and am excited to pump with them 🙂"
"This kit is so handy for a newly breastfeeding mom! My flange size changed throughout my first time breastfeeding so I anticipate that happening again with my second. It'll be handy as I continue to breastfeed and need to adjust sizes. I also like having all the sizes in the kit so I can try out which one works best. I highly recommend this flange kit!"
"Okay, this kit is hands down one of the best things I've gotten for my pumping journey! I love that it has all the different sized flange inserts available at your finger tips. Personally my flange size has fluctuated so much over this experience and it's great to not have to go out to buy each size hoping that they would fit. 10/10 would recommend this product"
"There is nothing like Willow flanges. They fit perfectly in the Willow Go and corresponding pumps. They are the most comfortable I have ever tried. I never have an issue with pulling too hard or aggressively, the silicon is definitely the way to go with pumping. I love the diversity of sizing that comes with this pack, as my size changes during postpartum. When I had my first son I was originally a size 21, then went to 17 and back up to 19 to then pump for 15 months. I can't wait to use this kit for my next pumping journey!!"
