No let down during first pumping session at work each day

alysonmh

I nurse exclusively while at home with LO and pump while at work. I've been back at work about a month now and just this week I've stopped having a let down during my first pumping session of the day at work. I usually pump 2-4 ounces but now at my first pump at work I only pump 1/2 an ounce and the rest of the day it's back to 2-4 ounces each time I pump. I can feel that I have milk in my breasts but I'm just  not getting a let down during that first pumping session. Has this happened to anyone, any tips for fixing it?
