HYDRATION: A Guide from Babies to Teenagers

Hydration plays a vital role in children's health, impacting everything from physical development to cognitive function. As children grow, their hydration needs change, making it essential for parents and caregivers to understand how to support adequate fluid intake. As a Paediatric Dietitian, iI believe this is an important topic, therefore have dedicated a whole blog to it! Read on to explore why hydration matters, the signs and risks of dehydration, and practical tips for keeping children well-hydrated.

1. Why Hydration Is Important

Water is the foundation of health, and for children, it is especially critical. Their bodies are made up of 60-75% water, depending on their age and size. Proper hydration supports:

  • Body Temperature Regulation: Water helps maintain a stable internal temperature, preventing overheating during physical activities or in hot weather.

  • Nutrient Transport: Water transports essential nutrients to cells and removes waste products.

  • Brain Function: Adequate hydration enhances concentration, memory, and mood, which is crucial for learning and development.

  • Digestion and Metabolism: Water is necessary for digesting food, absorbing nutrients, and maintaining a healthy metabolism.

  • Physical Performance: Muscles and joints need water to function effectively, especially during play and sports.

2. What Happens When Kids Are Dehydrated

Dehydration occurs when the body loses more fluid than it takes in, and in children, this can happen quickly. Factors like high activity levels, hot weather, illness, and inadequate fluid intake increase the risk.

Consequences of Dehydration:

  • Mild Dehydration: Can cause fatigue, irritability, and reduced cognitive performance.

  • Moderate Dehydration: Leads to dizziness, dry skin, increased heart rate, and darker urine.

  • Severe Dehydration: May result in confusion, rapid breathing, sunken eyes, and can be life-threatening if not treated promptly.

3. Signs of Dehydration in Children

Recognizing the signs of dehydration early is crucial. These can vary by age but generally include:

In Babies:

  • Fewer wet nappies (fewer than six in 24 hours)

  • Dry mouth and lips

  • No tears when crying

  • Sunken soft spot on the head (fontanel)

 

In Toddlers and Young Children:

  • Dry, cool skin

  • Lethargy or irritability

  • Dark yellow urine or infrequent urination

  • Sunken eyes

 

In Older Children and Teenagers:

  • Headaches

  • Dizziness or light-headedness

  • Fatigue or weakness

  • Decreased performance in sports or physical activities

4. What to Do When Kids Are Very Dehydrated

Severe dehydration is a medical emergency that requires immediate attention. However, for moderate dehydration, quick action at home can help.

Steps to Rehydrate:

  1. Oral Rehydration Solutions (ORS): Use ORS like Hydralyte, which contains the right balance of electrolytes and glucose.

  2. Small, Frequent Sips: Encourage children to drink small amounts of fluids frequently to avoid overwhelming the stomach.

  3. Breastfeeding or Formula: For babies, continue breastfeeding or offering formula alongside ORS.

  4. Seek Medical Help: If symptoms worsen or the child cannot keep fluids down, seek medical attention promptly.

5. How to Avoid Dehydration

Prevention is the best strategy. Ensure children drink enough fluids throughout the day, especially during activities that increase fluid loss.

General Guidelines for Fluid Intake:

  • Babies (under 6 months): Hydration comes from breast milk or formula.

  • 6-12 months: Small amounts of water can be introduced alongside solid foods.

  • 1-3 years: About 4 cups (1 liter) of fluids per day.

  • 4-8 years: About 5 cups (1.2 liters) of fluids per day.

  • 9-13 years: 7-8 cups (1.6-1.9 liters) for girls, 8-10 cups (1.9-2.4 liters) for boys.

  • 14-18 years: 8-11 cups (1.9-2.6 liters) per day, depending on activity level and gender.

6. Best Drinks for Kids

Not all drinks are created equal when it comes to hydration. Some are more effective and healthier than others.

Top Choices:

  • Water: Always the best choice for hydration.

  • Milk: Provides hydration along with essential nutrients like calcium and vitamin D.

  • Diluted Juice: Limit to small amounts to avoid excess sugar.

  • Oral Rehydration Solutions: Useful during illness or heavy activity.

 

Drinks to Limit or Avoid:

  • Sugary Drinks: Soft drinks, fruit punches, and energy drinks can lead to excessive sugar intake and poor hydration.

  • Caffeinated Drinks: Avoid coffee, tea, and energy drinks due to diuretic effects and potential negative impacts on sleep and behavior.

7. Other Tips for Increasing Hydration in Kids Who Are Poor Drinkers

Encouraging children to drink more can be challenging, especially if they are reluctant. Here are creative ways to boost hydration:

Make It Fun:

  • Flavor the Water: Add slices of fruit like lemon, lime, cucumber, or berries for a natural flavor boost.

  • Fun Cups and Straws: Let kids pick colorful cups or straws to make drinking more appealing.

  • Water-Rich Foods: Offer foods high in water content, such as watermelon, cucumber, oranges, and strawberries.

Set Routines:

  • Scheduled Drinking: Encourage drinking at set times, such as before school, with meals, and after playtime.

  • Reward System: Create a hydration chart with stickers to track daily fluid intake.

 

Model Good Habits:

  • Lead by Example: Let children see you drinking water regularly.

  • Involve Them: Let them help choose or prepare their drinks.

Conclusion

Hydration is a cornerstone of health for children of all ages, from babies to teenagers. By understanding the importance of adequate fluid intake, recognizing the signs of dehydration, and using practical strategies to encourage drinking, parents can help ensure their children stay healthy and hydrated. Make hydration a daily priority, and your kids will be better equipped for physical activity, learning, and overall well-being!
