A: Hi K--- If you are leaking, special care must be taken to avoid the build up of dried breastmilk on the shell parts and in the foam inserts. If the foam inserts become saturated, separate the shells, backs and inserts. The shells and backs should be washed with a mild soap or detergent in warm water, rinsed thoroughly in cold water and dried. Squeeze the milk out of the foam, then rinse them twice with clean cold water. Dry them by squeezing between a clean cloth or paper towel. SoftShells™ should be sanitized once a day. If you have just used the SoftShells, the foam inserts must be cleaned separately before sanitizing. Squeeze the milk out of the foam, then rinse them twice with clean cold water. The foam insert should be rinsed whenever it gets full as well. Dry them by squeezing between a clean cloth or paper towel. Separate and place the silicone back and dome in a small pan filled with cold water. Distilled water is recommended. Bring the water to a boil and allow it to continue boiling for approximately 10 minutes. Drain off the water and place parts on a clean cloth to dry. For quicker cleaning, Medela offers Quick Clean™ Micro-Steam™bags to make sanitizing the parts easier. We also offer Quick Clean wipes that can help take the place of soap and water when washing the parts throughout the day. Shells and backs can also be put in the top rack of a dishwasher. Just be sure not to place foam inserts in a dishwasher or Quick Clean Micro-Steam Bags. If you have any other questions, feel free to live chat with us on our website. We'd be happy to help! - Your Medela Customer Solutions Team

A: Hi Pat--- Thank you for your question. The SoftShells for Sore Nipples come in one size, they have a diameter of 40.83mm at the opening at which the nipple would go into. We hope this is helpful!

A: Hi Antye1998--- No, the foam inserts are not made with materials specifically intended for food grade purposes. the Medela Soft Shells are not intended for collection or storage of breast milk, nor has the product been tested for such purpose. Please consider chatting with us on our website if you have any additional questions. Have a great day! - Your Medela Customer Service Team

A: Only wear breast shells during waking hours. The reason that you would only wear them during the day is so that you do not have to worry about lying on them or having them shift. If they shift they could apply pressure to the wrong area. If you are awake, you will know if they have moved out of place or if the pressure is too much and be able to adjust them. You will not be able to pump while you have them on.
