I just was getting ready to pump at work and discovered I left the flange at home! Yikes. I last nursed DS at 7:30am (it's 10:50am now) and won't be able to nurse him again until 4:45pm. Should I go home and get the flange? I REALLY don't want to because the round trip is one hour and I'm a teacher and that will cause problems. Will it hurt my supply if I go 9 hours without nursing/pumping? Please advise!
