Eating WAY too much?!

My son is 7 1/2 weeks old and weighs maybe 11 lbs at most. Last time we went to the doctor was 2 weeks ago and he was 9lbs 3 oz. They told me the rule of thumb was whatever he weighs in KG he should be eating in oz. So we bumped him to 4oz at that time. Well after a week he was eating 5oz because he was still visibly hungry. That was kind of our platform for a while.

Now he is trying to eat 7-9oz!! I finish at 5oz and then he FREAKS. He is shoving his hands in his mouth trying to suck on them, and when I give him the paci he violently tries to get it in his mouth then spits it when he realizes no milks comes out. And so I give him a few more ounces and he downs it!

This is every 3-4 hours at that. We do take breaks and burp and what not every 1-2oz so he doesn't get gassy and recognizes when he is full.

What do I do?! Has anyone else gone through this? I left a message for his doctor, I just wanted to see opinions until I hear back.

For him to eat this much he would need to be at least 17 lbs for it to be an appropriate/recommended amount.
