i use size 36mm medela flanges on my pisa, as per my LC's measurement. I ep'd with #1 and they were fine and I've been pumping 6 mos for #2 while at work and they were fine too. absolutely no problem until recently.
For the last 2 weeks, no matter how i position my right boob, it is rubbing on the flange side and becoming raw. it has bled too, but quickly heals. i use a lot of lanolin on that side now, before and after i pump. it doesn't make much of a difference. when baby nurses on the weekend, i do not pump that side for 2-3 days, it heals nearly completely. and then starts again on monday.
i'm not ok with this cycle. today was particularly bad
i don't know whether i need to purchase a different size flange, and if so, what size.
i'm also at the 10 month mark and wouldn't be totally opposed to stopping pumping and providing formula at daycare and nursing morning and night if possible. i hate pumping, and am barely pumping enough to send to daycare anyway, so I also don't love the idea of buying flanges at this point, and i think i had a good run already.
