Is this too much milk for a 7 week old baby?

My little boy is 7 1/2 weeks old and weighs approx 5 kgs. today i gave him his first bottle of 3oz of expressed milk. He was still hungry after i fed him so i fed him for about another 10 mins. So i'm uming he had about 4-5oz of milk. Is this too much for a 7 week old baby?
