Choosing the correct flange insert size is essential for comfortable and effective pumping. If you experience nipple swelling or discomfort while pumping, it may indicate an unsuitable flange size. We recommend closely observing the appearance of your nipple during pumping to ensure the proper fit, and if necessary, replacing the flange insert with the correct size.
