Growth spurt

Okay so I have a 3 month old (May 8) and for the past 3-4 days he has been eating anywhere from 3-6 ounces i don't what to do. He's hungry and eats then falls asleep when I put him down he'll maybe sleep for 15-20 mins and scream and then I make him 2 ounces. I'm losing my mind.. HELP
