Does he drink the entire 6 oz. in one sitting? And let's say he woke up at 8 am today, 12 ounces equates to about 4 ounces every 3 hours almost... Your time I believe. That doesn't sound bad to me.

today he's had 12oz in formula and 30 min on the boob today. 5 min each feeding & he's currently working on a 6oz bottle @breloya

Doctors told me I was over feeding my daughter and I was listening to them. She started to lose weight and always cried for more food, so I started feeding her more. She started to gain and be happier. Go with your gut feelings. ❤️

How much does he eat? And is he spitting much up after each feeding? Every baby is different. Some eat a bit more than others.
