baby requested more milk than recommended dose

Hi my baby is 1 month 7 days. She has been taking 90mls every 3hrs however recently she seem to be wanting it every 2hrs for every meal. noted that the recommend dose online for fomula milk is between 720-780 mls per day. if i were to give every 2hrs with 90mls, her daily intake will be ard 900mls. how much milk do mummies give their baby ard this age?
