## Description

Why choose Momcosplay Wearable Breast Pump Flange Inserts? Momcosplay Flange Inserts 15/17/19/21mm are designed for moms and are compatible with 24mm flange/shields for most breast pumps. You may not know the size of the flange insert. Flange size is not associated with chest size. You can use the link image guide to measure the best flange size. This can improve the efficiency and comfort of breastfeeding. As some mothers experience swelling of their nipples while expressioning, observing the appearance of their nipples is important. The flange size is large for comfortable and efficient pumping. Never rub your nipples or squeeze them by flange channels. All nipples must fit in the flange channel and be free to enter and exit. If you feel uncomfortable while pumping, you may not use the appropriate size flange and need to replace it with a new size flange. Some moms may require a different flange size on each chest, which can change over time. Therefore, it is recommended that you select the correct flange size after the exact measurements. If you have any problems during use, please contact us in time. We will give you different release solution as soon as possible to solve your problem. Note: Flange insert 13/15/17/19/21mm is only suitable for 24mm shield/flange, not suitable for 27mm shield/flange or other size.

Review: First my mom cozy and my Medela. Perfect
