It’s okay to miss a session. This happens to me all the times 😂 Just quickly pump it out and clean yourself. Change out to a clean clothes.
Pump asap. After that, feel your boobs for any hard areas to make sure that you've emptied them out fully
Massage your breast before pumping. Can use milk collector or breast pad so it will not wet your shirt
change out asap & use BM collector just in case
