    Default are my pump horns the wrong size?

    Hi ladies
    advice pls.

    I'm using the mendela pump in style and find that compared to manually using my hands to express milk, using the pump expresses much less.

    I am wondering if it is because the breastshields(size M) are too large for my nipple.
    My nipple hurt after pumping,they feel like they have been sucked out. During pumping, some aerola is sucked into the funnel. I was wondering if this is an indication that the funnel is too large?
    I have measured my nipple size before pumping and it is 17mm. (the nipple does swell during pumping though)
    Shld I get size S shields(21mm) or is the standard M a better fit?

    yes. go for the next size. The aerola is supposed to stretch and lengthen during nursing/ pumping. If you are having better outcomes using hand expression, you can collect your milk that way.
    are you pumping b/c you are back to work?
    maybe it is the time of day you have set aside to pump. Is your pump yours or is it a borrowed one? sometimes it is the physical pump that is no longer functioning.

    The soreness after makes me think they are too small.

    I had this problem too & my shields were too small. The larger medela ones made me sore too but they are worth a try For me, the most comfortable shields i found were the pumpin pals (just google them for info), but i know some people don't like those. I us ethe large size of those & still have some pain but it's not nearly as bad. I would definitely get some different shields though...it took me a long time to figure what was causing my nipple pain & it got pretty bad. My pump is also a PISA...make sure you don't have the suction too high. This will cause more pain & actually get you less milk w/the pump. Just a side note too, if you try the pumpin pals - I use a bit lower suction level w/those than I do w/the medela shields.

    Good luck! & don't be afraid to experiment a little to find what is most comfortable for you, esp if you plan to do lots of pumping.

    Shields that are too big can cause soreness too. That was my problem, and going down a size helped a lot. Both Medela and Ameda have images on their websites to help you determine if your shields are too big or too small. It's a little difficult to compare yourself to an idealized drawing, but it can be somewhat useful for troubleshooting.

    Pumpin Pals work great for me, although I use them with a manual pump. I just couldn't get the double electric to work well for me,
