Love this
This is a great kit for first time pumping moms who need direction on flange sizing. The ruler helps you find your size. It includes lots of flange inserts to get your perfect fit which is very convenient. Instead of having to then order the correct size you already have the options in this kit.

Made my life so much less painful!!
Definitely worth the money! Having multiple size flange inserts that worth with both my Medela and Lansinoh pumps is wonderful. Being able to pump without the overwhelming amount of pain from the incorrect flange sizes has been such a relief. Using the sizing guide to measure and having the correct flange inserts in the kit along with the sponge thing to clean them has made my life so much more comfortable, as well as easier. I’m not struggling as much to empty completely anymore. I gave some of the smaller sizes I didn’t need to a few moms in the NICU that were going through the same thing after they measured themselves. I had originally planned to donate the sizing guide and leftover flanges to the lactation nurses to help them better measure other moms in the NICU however they couldn’t take them.

Loved this kit!
LOVED that it came with a ruler this helps so much as my body makes changes and I’m able to find out easily what my flange size is to get maximum output for my pumping sessions.

Very well organized nipple sizing set
These work great. Not sure if it’s Increasing my milk, but it’s doing its job. It lets you know what size the nipple is as well with the measuring card. It fits into my medela hand pump.

You’ll be glad you bought this before your baby comes!
Was very helpful! Had no idea I would need this and made my pumping experience better from the start. I brought this with me to the hospital and the nurses helped me confirm my sizes!

Definitely worth it!
If you’re on the fence about ordering this, definitely do it! It fits perfectly into my medela hand pump, the flange inserts into the flange that it already came with it. The first picture shows what I’m explaining. My hand pump came with a size 24mm and I’m a 19mm so definitely a huge difference. It actually doesn’t hurt when I pump now and I get more milk too. Not expensive and made well! Very comfortable too.

Pumping mom life savers!!!
These saved me once I finally got them. I was pumping with the regular hard plastic flange with no inserts and these really do help especially because you really do have to pump over and over and over especially if your baby is like mine and doesn’t like the breast for whatever reason😭 would not recommend pumping without these if your pump is not already your size!!

YOU NEED!
YOU NEED THIS! I did a comparison of how quickly milk started coming out using the 19MM, 21MM, & the 24MM. The 24MM is what I was using for the past 2 months. The 19MM INSTANTLY started giving me more milk more efficiently than the 21MM & 24MM. I’m a 19MM & have been missing out on extra milk I’ve left in my ducts when pumping. 🤦🏽♀️

Amazing
After using the wrong flang size and wondering why pumping was causing pain this was a life saver. The measurements are spot on and the adjusters fitted right into my current pump. Huge difference in comfort and milk output.
