I used my pump last night for cervical ripening (advice from my midwife). I pumped about a teaspoon or so of colostrum (hooray), but I noticed that a lot of my areola was being sucked into the breastshield that came with the pump. After looking through the booklet, it looks like the standard size is too big. I had colostrum leaking out the sides & down my belly. ATTRACTIVE!

Anyone else have this issue? I saw on the Medela site that I could buy two new breastshields in their small size, but they also have 21mm (small) "inserts". The site doesn't have descriptions though, and I wasn't sure if the insert was to put inside the standard shield. It's only a $10 price difference, but I don't want to get the wrong thing.
