Requested by many Spectra pump users, Maymom develops this special kit just for Spectra users who have small nipple diameters. Spectra does not have this size of flange. It is only available from Maymom.

Please note that for hygiene purpose, no returns will be accepted once item seal is broken. Breastfeeding accessories are personal item.

Maymom Breastshields Selection

  1. Measure your nipple diameter (N) using a nipple caliper.
  2. We suggest that you start to try a breastshield size (B) that is 2-3 mm larger than your nipple diameter
  3. Or just follow the following table


Note: If you already have the yellow adaptor, or if you are buying multiple flanges, you can opt for the flange without adaptor at a slightly reduced cost. Both are the same except the adaptor included in this listing. See link below:



We also have flange set available,  everything you need for a double pumping including bottles adaptor and backflow protector for your conveniences. See link here.



New! For those with Medela Freestyle, Avent Comfort pump or Ameda purely yours, you can choose the following option to use Maymom smaller breastshield with the pump! 
Brand New Sealed in Package

  1. Satisfactory 4 Star Review

    Posted by on 5th Apr 2017

    It works but is not as comfortable as Spectra brand and has fewer silicon membranes. However, it has the narrower neck, so this is good. The adapter part is difficult to connect and disconnect, though.

  2. Great conversion flange 4 Star Review

    Posted by on 8th Mar 2017

    Fits my spectra pump well. Been great to able to use the smaller size

  3. Didn't think it could have such an impact 5 Star Review

    Posted by on 23rd Jan 2017

    I realised after 2 months of pumping that i was using the completely wrong size flange. I ordered a new one after using a measuring tool and i can't believe how much time i wasted with the wrong size

    Came with all the attachments i needed plus the ability to still use the flange with other pumps.

    Am so happy with my purchase

  5. Thank you 5 Star Review

    Posted by on 9th Jan 2017

    Finally I can pump without pain. I can't believe the difference it makes actually having the right size. Thank you so much for making the smaller sizes. They fit right on to my spectra dew pump and bottles and I am so happy with the quality. I only wish I had found these with my first child!!

  6. Just what i needed 5 Star Review

    Posted by on 19th Dec 2016

    I bought the smaller size as the ones that came with my spectra were way too big. I am now pumping a lot more and no more pain.

  7. Great product thankyou smilingbabies 5 Star Review

    Posted by on 1st Nov 2016

    Love these ! I don't fit the standard spectra flanges however these have to come to my rescue. I actually prefer them! They fit all my existing bottles (slim neck) which has saved me lots of money not having to switch over to wide neck.

    Thanks !
