Anyone with a 2 month old, how much do they drink every some many hours?

Just a question, I know every babies different. But the app told me at 2 months baby should be drinking 6-8 ounces at 2 months every 4 hours or maybe longer stretches. Just curious about how much they drink & how far apart you give it to them.
