I only have time to pump 2x at work and I had been keeping up with my boy. He eats 3-3.5 oz 3x at day care. I only got 4 oz this morning and will pump again in2 hrs. (i do 1130 and 230) is there anyway to increase how much i pump at one time? I know women that can get 11 oz!!!!!!! I would just like to get 6 or 7.
