My daughter is 6 weeks old and I am trying to start pumping to go back to work. In the morings I can get about 4 oz combined from both breast. But during the day I can only get about 1 oz out of each. I worried that when I got back to work in 2 weeks she will not have enogh food. Does any one have any tips to increse my supply or tips for pumping. She nurses every 2 to 3 hours usually. Please help!!!!!
