The amount of fluid a child needs depends on factors such as their age, size, activity levels and the weather. The guidance below provides a general guide based on recommendations from the European Food Safety Authority:

• Infants (0–6 months): 100–190ml per kg of body weight per day
• Infants (6–12 months): 800–1000ml per day
• Children (2–3 years): 1300ml per day
• Children (4–8 years): 1600ml per day

How often should children have water during the day?

During hot weather, it's especially important to offer water regularly throughout the day and ensure it is easily accessible.

Breastfed babies do not usually need extra water, as breast milk naturally adapts during hot weather to provide more fluid. Formula-fed babies may benefit from additional water when temperatures rise.

For babies under 6 months, any water offered should be boiled and cooled. From 6 months onwards, freshly drawn tap water is suitable.

Some foods are also a good source of fluid such as fruits and vegetables, watermelon and cucumbers are a great example of this, also yoghurts, homemade ice lollies and dips such as tzatziki.

How can you tell if children are drinking enough?

Young children don't always recognise when they're thirsty, so regular reminders and easy access to drinks are important.

Signs of dehydration can include:
• Fewer wet nappies or less frequent urination
• Dark yellow urine (well-hydrated urine should be pale straw coloured)
• Dry lips or mouth
• Tiredness, irritability, confusion or unusual floppiness

Keep water within easy reach and encourage regular sips throughout the day.
