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.
How long should you pump? In short, you should pump until milk isn't coming out any more. Or, if you're trying to boost your supply, pump a little while longer after the milk stops flowing. I'm just not a clock-watcher, I think you should do things until they're done. But, in general, pumping for 15 minutes should do it for most people. If you're having trouble letting down for the pump, read the section on Better Pumping just a bit further down this page. There is no harm in pumping for a few minutes after the milk stops flowing, and it's a great way to send your body the message that more milk is needed (if it is).
