Another way to keep up your milk supply is to pump regularly when you are not nursing from your breast or are away from your baby for more than a few hours. If you are away for the day at work, my breast pumping schedule would be to pump every 2-3 hours for about 15 minutes or so.
To figure out how many hours you need to run your pump, you need to know how fast your pump works. You will need to find the gpm or gallons per minute of water that your pump circulates. You can find this out one of two ways: by either looking in your manual that came with the pump or by calling the manufacturer.
