Bottle schedule?

How much formula and how often is your 3.5 month old taking a day? My girl was taking 5 oz every 3 hours (besides her first morning bottle after waking which is 6 oz), now she goes more like 4 hours, meaning then she’ll only get 5 bottles per day rather than 6. I can’t remember from my first two babes how long they are supposed to go between feedings. She’s a big baby so I know she’s not starving but really need to get on a better schedule! Also trying to get a better schedule down so we can put her down for bed earlier like around 7:30 vs 9. Help!
