DS is 11 weeks old, about 13 pounds. I just went back to work and am figuring out the science and art of pumping! I've been trying to pump every 2-3 hours that I'm away from him. I get about 2 1/2 ounces in 5-10 minutes. That's where I stop, since I read that we make about an ounce per hour. I go home during breaks in the day and nurse him when I can, and I want to be sure to have plenty of milk for him then. Am I correct that a baby his age only takes about 24 ounces per day? But when he gets older/bigger, won't that increase? When should I aim to pump more? Or should I just keep pumping until the milk stops flowing?
