How many ounces in bottle for breastfed baby?

S • 24. Married. First time Pregnant!

I’m trying to figure out how many ounces to feed my 6 week old. I’ve been doing 2.5 oz. in an emergency bottle or if we’re headed somewhere with a backup on the side so I don’t contaminate it all. But I can never tell if 2.5oz. is enough. I also don’t want to overfeed as I know that’s easy to know while bottle feeding. Any mommas willing to let me know how much their kitties typically eat when bottle fed?
