How Much Water Should Kids Drink? A Simple Daily Guide for Parents

How much water kids should drink each day depends on their age, activity levels, weather, and whether they’re feeling unwell.
 
There’s no one-size-fits-all number, but simple daily targets can help guide you. Use the age-based table below as a practical starting point and adjust as needed for your child’s routine.

• Supports everyday body functions like temperature regulation and digestion
• Helps maintain focus and overall wellbeing throughout the day
• Plays a role in physical performance during play and sport
• Supports healthy energy levels for school and activities
• Helps keep the body functioning smoothly during growth and development

Needs can vary from day to day, and building good hydration habits can happen gradually.

• Hot weather: Offer water more frequently and encourage regular sips
• Physical activity / sport: Pack an extra water bottle and prompt drinking before, during and after activity
• Fever: Offer small amounts of fluids often and monitor intake
• Vomiting/diarrhoea: Provide frequent sips and keep an eye on hydration signs such as urine output

Mild dehydration: common signs

• Feeling thirsty
• Darker yellow urine
• Urinating less often
• Dry mouth or lips
• Tiredness or low energy

Severe dehydration: when to seek urgent help

• Very sleepy or difficult to wake
• Little to no urine output
• Sunken eyes
• Appears very unwell

• Encourage regular sips rather than waiting until they’re very thirsty
• Pack a water bottle for school and outings
• Increase water intake on hot days or during sport
• Make water part of daily routines (e.g. after brushing teeth or before leaving the house)
• Lead by example and model regular water drinking
• Use gentle reminders to encourage consistent habits
