Hi, I have a 2 month old and I will be returning to work in a few weeks. I started pumping to store milk but I am having a hard time getting any milk with the pump. I barely make it to 2 ounces when I pump after I nurse him. When he was first born I used to pump around 8 ounces...I stopped because I finally got him to latch on perfectly and have been nursing exclusively ever since. But now that I have to go to work I need to be able to pump more than 2 ounces. What can I do???
