Tilting if the breast shield may lead to leakage of breastmilk. Please sit up straight while pumping to ensure the breast shield does not tilt.
It is important to find the maximum vacuum level that is comfortable for you as pumping at uncomfortably high vacuum level may cause pain and hinder your milk flow.
To determine your own maximum vacuum level, use the vacuum level and cycle speed controllers buttons on the breast pump to increase the intensity until pumping feels slightly uncomfortable ( not painful), then decrease the intensity slightly.
On average, a typical expressing session goes for 10 - 15 minutes, but this is just a guide and may vary for each individual.
Upon completion of pumping, do not just pull away the breast shield in its sealed state, but instead turn off the power first and remove the breast shield slowly by breaking the seal between your breast and the breast shield with your finger.
