How many oz of milk does your 1 month old baby get?

Mine eats 5 oz every 4, 5 hours, even 6 at nights, is it normal, or shouuld I give her more, cuz sometimes she would be satisfied after a feeding and sometimes she would still stick out her tongue but then I would give her a pacifier and she would calm down, so I dont know, should I give her as much milk as she will eat, or just give her 5 oz, cuz I read for her age, thats the most she could eat!
