How much milk?

Lately during my early morning pumping session I have been filling up the bottle on my right side. The left still has room for about 3 more ounces. It is so weird because in the past it has always been the opposite. I need bigger bottles. The bottles I use now hold about 6 ounces maximum. I have a few bigger bottles at home that will fit my pump but they are made of glass. They are just too heavy for my band to hold up hands free especially when they are full. So, I bought three big plastic bottles today. They should work just fine. I'll wash them tonight and try them out in the morning. I am still pumping a lot more at work than I am at home. I think it is because I am not distracted at work. I have my quiet little storage room where no one bothers me and my book and I pump away. At home on the weekends or on days off I have all these little people clamoring for attention. My plan was to take off some more days this Spring but maybe I'll go to work in the mornings and just take off early so I don't mess up a good thing. That would have to be the strangest reason to ever want to go to work!!
