How to maximize pumping of milk and the same time satisfy your baby in between the feedings?

I have a 2 month old baby boy who is quite a feeder. I try to pump 1 hour after every feeding and later when I feed him, he is hungry for more. Naturally since i pumped an hour before he must have got hungry early on, but later on during every feeding he seems to be wanting more shortly after being fed.please advice.
