I’m Crystal, mom of three and surrogate to five babies and I’ve exclusively pumped through it all.  In struggling with elastic nipples myself, I found there were no inserts on the market that worked with all of my pumps and were long enough to cover the stretch of my nipples.

I’ve helped size thousands of moms and I knew that I was not alone in my quest for the perfect inserts. I’ve dedicated the last several years to creating solutions for a successful pumping journey.  So, I created a better product for moms with elastic nipples, but not just elastic nipples! These inserts will work for all nipples and can be used with any pump on the market!
