A 9-month-old baby can have 4 to 8 ounces of water per day, in addition to breast milk or formula

. A healthy 9-month-old needs between 1,000 to 1,250 mL of fluid daily, which equals about 4.5 to 5.5 8-ounce cups

. Water recommendations for babies can vary, so check with your health department or pediatrician for specific recommendations

. It is important to note that babies under 6 months old should only drink breast milk or formula because water can be dangerous for them at that age

. After 6 months, you can offer water, but breast milk or formula should still be prioritized
