My baby is 3 months old and she is on formula fed . But she drinking only 60 ml . I am worried about her fed , please help me

A. 3-month-olds will generally drink 4 to 6 ounces of formula around every four hours. That adds up to 24 to 32 ounces of formula in around six feedings total in a 24-hour period. 4-month-olds will often drink 5 to 7 ounces of formula every four to five hours.
