1 month old wants to eat more frequently than recommended- HELP!

My son was doing great. I worked him up to 4 oz every 4 hours. Over night he has flipped a switch and is crying with all hunger cues about every 2 hours and still wants to eat 4 oz. He is formula fed and all the guidelines say this is way too much. He seems to be even more hungry throughout the night. Is this normal? What do I do?
