It is crucial to use the correct size of flange insert for both comfort and efficient pumping. Some mothers may experience nipple swelling while pumping, so it is important to monitor the appearance of the nipple during the process. To ensure optimal performance, it is recommended to replace the flange insert every 1 to 2 months.

These breast pump accessories are made of transparent silicone material and are BPA-free, allowing for safe use. After each use, the replacement pump parts should be washed with warm soapy water and rinsed thoroughly. Using coconut oil or nipple butter can reduce friction and make them easier to use.
