Im back at work and travel to different offices during the week. Some times I get to pump 3 times a day others only 2 times. Im worried this may effect my supply. I also dont get to pump at the same time each day, will this effect it too? I usally end up with 10-12 oz. by the end of the work day. So if I end up with less then 12 I pump after LO goes to bed. Any advice? Thanks!
