Medela PersonalFit Small 21 mm Breastshields, 2-pk

Comment: Best thing is that nipples don't get sore anymore, like when I was using the standard size. Getting the proper size breast shield matters and make a difference.

Comment: Fit matters for comfort and efficiency. The standard 24mm that comes with the pumps was too large for me. I figured I would try the smaller size despite the fact that they were hard shell as opposed to the soft-fit that comes with the Freestyle pump. I was shocked at how much more comfortable pumping sessions were with the smaller size. The efficiency increase was another surprise. I recommend figuring out what size you need and getting that, not defaulting to what comes with the pump.

Comment: I bought the Medela hand pump which came with the 24mm Breast shield. That one was too big and kept leaking milk out of the bottom. The 21 mm is perfectly fine. I was nervous since it was not the comfort shield. but it is totally fine and I barely noticed a difference in comfort. Very easy to clean and comfortable on the breast.

Comment: I bought the Medela pump and on the first day of use felt pain and discomfort while pumping. I thought I am using the wrong size breastshield and I ordered these the same day. It took almost one week for the product to arrive and by then I kept feeling better everyday with the 24 mm shields. I didnt notice an increase in supply or improved comfort with these 21 mm shields. I just needed to get used to the pump. Do wait for atleast a week to see if the shield size is the problem.

Comment: (under my wife's direction) Having the right fitting breast shield makes a huge difference during pumping sessions. These worked like a charm with my hands-free unit.
