breast feeding question

Robyn

my little man is 1 week today. my milk came in at day 5. any tricks to get my milk to come in faster. my breast don't feel full for a couple hours after feeding. would like to get my supply built up. I tried pumping but again milk doesn't come back for several hours and if he gets hungry I tried to feed from breast but he doesn't get enough. I end up given him what I pumped. help ladies please, I'm desperate!
