im feeding my baby to much?

Why do people need to tell me how much my child should be eating its pretty annoying... This is my second child! I gave birth last month march 10th he came out at 38 weeks. Weighing 6 pounds 14oz. I decided i wanted to breast feed and bottle feed as well. He wouldnt latch due to my inverted nipple the nurses helped with nipple shields my baby wouldn't latch and if he did he wasnt getting enough :( anyways we decided formula he was drinking 3-4 oz every 2 hours!!!! the nurse would come in and talk junk to me telling me not to feed him that way thats to much etc. But when i wouldnt he'd cry for more. Hes now a 6 weeks old and drinks 3-4 oz sometimes 5 every 2 hours or half and hour hell have 2 oz. He weighs now 10 pounds 11oz hes gaining a little weight. He doesnt throw up when he drinks it all he does burp alot and doesnt complain what do you guys think? I get they have small stomachs but my son seems fine.
