Working Mum: Juggling work & Drop in Supply

Anyone experienced drop in supply after starting work in the office? How often do you pump & how do you also manage your time at work to pump? I’ve heard stories where for some, their supply dropped due to baby being away for a distance or they pump lesser leading to drop in supply. I exclusively pump and my maternity will soon be over. Trying to mentally prepare myself what’s to come & in hopes to prevent low supply #firsttimemom
