Acting hungry 24/7 now😓

My son is two weeks old and for the past two nights it’s seems like he can’t get enough food when it hits 10pm he will drink 3oz of formula and 10 minutes later basically act like he’s hungry again. He won’t stop crying until you feed him n it will last for hours. 😓 i don’t know to think it’s a growth spurt or overtired or colicky. Any advice of how to get through this or what it is?
