I have a medela pump and am having problems getting the right fit breast shield.
A 24mm is too large - it sucks up too much of my areola and leaves my areola red and sore. A 21mm is too small - my nipple rubs on the sides and gets raw (even if I use coconut oil for lubricant). I bought a 22mm insert for the 24mm shield from Maymom and am having problems with that too. My nipple seems to fit well without rubbing and my areola does not get sucked up. However, I get a ring on my areola where the insert stops and meets the larger breast shield. I pumped with the insert for 2 minutes and now have bruises in a ring from the insert. Any way to fix this problem? I am getting extremely frustrated with getting the right shield size and am considering buying a totally different brand pump. I start work in a week and am trying to get a storage supply but it is slow going because I just can't seem to get the right shield size. Thanks for your advice.
