How Much Water Should a Child Drink?
Age-appropriate hydration guidelines to keep your child healthy and energized.
Children's water needs vary significantly by age, weight, and activity level. As a general rule, kids aged 1-3 need about 4 cups per day, ages 4-8 need about 5 cups, and older children need 7-8 cups daily. These amounts include water from all sources, including food and other beverages. Active children or those in hot climates may need considerably more.
Water Needs by Age Group
Toddlers (1-3 years)
About 4 cups (32 oz) of total fluids per day. This includes milk, juice, and water from food. Offer water regularly throughout the day in a sippy cup.
Young Children (4-8 years)
About 5 cups (40 oz) of total fluids daily. Encourage water over sugary drinks. Pack a water bottle for school and activities.
Older Children (9-13 years)
Boys need about 8 cups and girls about 7 cups daily. Active children in sports may need significantly more to replace sweat losses.
Teenagers (14-18 years)
Boys need about 11 cups and girls about 8 cups daily. Teen athletes should drink before, during, and after practice or games.

Frequently Asked Questions
Can babies drink water?
Babies under 6 months should not drink water as breast milk or formula provides all the hydration they need. After 6 months, small sips of water can be introduced alongside solid foods.
What are signs of dehydration in children?
Watch for dry lips and mouth, fewer wet diapers or less frequent urination, dark yellow urine, crying without tears, irritability, and lethargy. Seek medical attention if symptoms are severe.
Is juice a good source of hydration for kids?
While juice does provide fluids, it is high in sugar. The AAP recommends limiting juice to 4 oz daily for ages 1-3 and 6 oz for ages 4-6. Water and milk are healthier hydration choices.
Should children drink sports drinks?
Sports drinks are generally unnecessary for most children. They contain added sugars and are designed for prolonged intense exercise. Water is the best choice for everyday hydration.
How do I know if my child is drinking enough water?
Check their urine color. Pale yellow indicates good hydration. Also watch for signs like energy levels, mood, and how frequently they urinate throughout the day.
