How much you can pump depends on a lot of things; age of the baby, pump you are using, if you do massage before & during pumping, if you pump both breasts at once, location of pumping, experience, length of time pumping, time of day, stress, breast differences, and other factors.
If you have a young baby and are not using any massage, then getting 4 ounces is great! Little babies stomachs are tiny and breasts don't need to make much milk.
For info on massage go to google and type in Marmet technique. Breasts can make different amounts of milk. They can have different gland structure. The baby may suckle better at one and that one makes more milk. It might be a one time thing.
People recommend all kinds of things to increase milk that haven't been scientifically proven. The way to increase milk is to breastfeed and/or pump more.
