Is it true not to give a baby more than 32oz in 24 hours?

My 6 week old baby wants to eat 5oz every 3 hours sometimes 6oz! I’ve tried to make him wait four hours in between or just drink 4 ounces but he hates it and cries :(. He was born 9lb 5oz so he’s a big baby. I don’t want to over feed him but don’t want him to be hungry. I know everyone will say ask my pediatrician and I will, but I want a second opinion.
