How to transition from pumping to breastfeeding?

I've been an exclusive pumper since my baby was like 2 days old....he is now one month. We've been working on breastfeeding and with the help of nipple shields it seems like breastfeeding might work out. But I'm not sure how to transition. I pump about 6 oz every 3 hours but my baby only eats 3-4 oz every 3-4 hours. So when he breastfeeds my boobs are not empty and then I have to pump....so I've doubled my work -_-

How do I do this? Just drop pumping completely, live with engorment for a few days, and let my supply drop?

Any advice?
