How many ounces of water should I give my 10-month-old baby in a day?

7months na baby ko, nag start sya kumain nung 6months, advice ng pedia ni baby kung pwede daw is breastmilk or formula ang ipainum hanggang mag 1yearold kahit pa kumakain sya. specially kung ung mga cereal(cerelac), processed baby foods yung ipapakain.
