Please help. Baby eating all the time!

Calling all mommy friends! It seems that Lucas turned a month old and wants to kill me. Before he'd stir a little to let me know it's time for a diaper change and feeding. He'd take 3-5 oz of breastmilk every 3-5 hrs. Well, now he just wakes up and cries to the point of choking, eats, and falls asleep. When I try to burp him, he screams until I put the bottle in his mouth. One feeding was at 6 pm was 4 oz, then again at 8:30 3 oz. I change his diaper, offer him a paci, and try to burp and smooth him. Nothing. He had a growth spurt at 2ish weeks.
