Every mom's needs are distinct. That's why to optimize your pumping experience you need the correct insert size. 

It's essential to ensure that the inserts provide a proper fit for your nipples. Inserts that are too tight or too loose may cause discomfort or hinder milk expression efficiency. 

Breast size can change during the breastfeeding journey, so we recommend re-evaluating your nipple and flange/insert size periodically.
