CARING AND CLEANING GUIDELINES:
- Sterilize before first use by submerging the inserts in a deep and wide pot of boiling water for 3-5 minutes. The inserts should be fully submerged in water and not touch the bottom or sides of the pot. Do not sterilize and avoid using high heat after initial sterilization.
- Hand wash in warm soapy water then rinse clean after subsequent uses. Using cold sterilization or UV sterilization is also permissible.
- Do not wash inserts in the dishwasher.
- Replace every 3 weeks, depending on the frequency of use.

Love these inserts! They’re so comfortable and I see an increase in my supply when I use them.
Thanks to the wide coverage, my pumping journey is sorefree!
Saw someone recommend this with the medela cups which is what I use and it definitely made my pumping sessions more comfortable. Noticed a slight increase in my output as well. The only downside is the flanges are on the pricier side.
Best insert ever.. output increase a bit using this inserr.
Bought extra for use with the cups. Effective.
