I have been pumping since my ds was born, he's now 8.5 months. I pump 3x's a day at work to make bottles for while i'm gone, but lately I am having a hard time getting a let down when I pump. Any suggestions?? I am worried because then I am not emptying the breast and I don't want supply to go down. Also then ds doesn't get the fatty hind milk...he's skinny enough regardless of how much he eats and any extra fat is needed!! NOt sure what to do!
