| ⚠️ Call Emergency Services Immediately If…
Your child is unresponsive, won’t wake up, has a seizure, has not urinated in 8+ hours, has sunken eyes with rapid breathing, has bloody vomit or stool, or has a sunken soft spot on the head (infants). Do not wait. These are signs of severe dehydration. |
Why Children Are at Higher Risk
A child’s body is up to 75% water (versus around 60% for adults). They lose fluids faster through breath, sweat, urine, and diarrhea. Their thirst signals develop later than their loss rate. By the time a young child says ‘I’m thirsty’, they’re often already mildly dehydrated.
Common triggers: vomiting, diarrhea, fever, hot weather, refusing to drink, prolonged play in heat.
Age-by-Age Symptom Guide
Infants (0–12 months)
They can’t tell you anything. You watch:
- Fewer than 6 wet diapers in 24 hours
- Sunken fontanelle (soft spot on top of head) — a serious sign
- No tears when crying
- Dry mouth and lips
- Sunken eyes
- Cold or mottled hands and feet
- Listless or unusually sleepy
- Skin that stays pinched up when you release it
Toddlers (1–3 years)
- Dry diapers for 6+ hours
- Crying without tears
- Refusing to drink (counter-intuitive but common)
- Cracked lips
- Unusually quiet or irritable
- Dark yellow urine
- Refusal to play
- Sticky or dry tongue
Children (4–10 years)
- Headache and dizziness
- Dry mouth and lips
- Fatigue, lethargy
- Less frequent urination, darker urine
- Slight irritability
- Reduced sweating in heat (warning sign)
- Sunken eyes
- Refusing food or fluid
Teenagers (11+ years)
- Similar to adult symptoms
- Headache, fatigue, dark urine
- Dizziness when standing
- Reduced sports performance
- Constipation
- Dry skin
- Muscle cramps during sports
Severity Levels: How Bad Is It?
| Severity | Signs | What to Do |
| MILD (3–5% fluid loss) | Thirsty, slightly dry lips, normal alertness | Home care with ORS or fluids |
| MODERATE (6–9%) | Dry mouth, no tears, sunken eyes, reduced urine, irritable | Aggressive ORS + see pediatrician same day |
| SEVERE (10%+) | Lethargy, very sunken eyes, no urine 8+ hrs, cold extremities, sunken soft spot | Emergency — go to hospital |
Two Home Tests Every Parent Should Know
Test 1: Skin Pinch (Turgor Test)
- Pinch a small fold of skin on the child’s abdomen between thumb and finger.
- Hold for 1 second, then release.
- Healthy skin snaps back instantly.
- Skin that stays pinched for 2+ seconds = moderate to severe dehydration.
Test 2: Capillary Refill
- Press firmly on the child’s fingernail until it turns white.
- Release and count how long until pink returns.
- Normal: under 2 seconds.
- Over 3 seconds = poor circulation, likely dehydration.
The ORS Solution — Why It’s Better Than Water
World Health Organization has recommended ORS (Oral Rehydration Solution) for over 50 years for child dehydration. It’s saved more children’s lives globally than almost any single medical intervention.
Why it works: pure water doesn’t replace lost salts. ORS contains the exact balance of glucose and electrolytes that the small intestine absorbs efficiently — even during diarrhea.
How to Give ORS
- Mix one packet in 200 ml of safe (boiled or filtered) water
- Cool to room temperature
- Give small sips every 1–2 minutes (not big gulps)
- If the child vomits, wait 10 minutes, then try smaller sips
- Continue feeding normal food alongside ORS
Homemade Emergency ORS (If Packet Unavailable)
- 1 litre safe water
- 6 level teaspoons sugar
- Half a teaspoon salt
Mix until dissolved. Use the same way as packet ORS. Replace with proper ORS as soon as possible.
Fluids That Help vs Fluids That Hurt
| ✅ GOOD CHOICES
• ORS solution (first choice) • Coconut water (older children) • Diluted fresh fruit juice (50/50 with water) • Plain water (mild cases only) • Breastmilk or formula (infants) • Clear soups, broth • Buttermilk (mild cases, no diarrhea) |
❌ AVOID
• Plain water alone in severe cases • Full-strength fruit juice (worsens diarrhea) • Sports drinks (wrong electrolyte balance) • Soda and aerated drinks • Tea or coffee • Sugary milkshakes • Energy drinks of any kind |
Common Triggers Parents Often Miss
- Hot afternoon play without water breaks
- Fever — even low-grade fevers raise water loss significantly
- Mouth ulcers — child refuses to drink because it hurts
- Stomach flu — fluid loss outpaces intake quickly
- Excitement at school/play — child forgets to drink
- Travel in cars without AC
- Cold dry winter air (yes, kids dehydrate in winter too)
Prevention: Daily Water Needs by Age
| Age | Daily Water Needs (Approx.) |
| 0–6 months | Breast milk or formula only |
| 6–12 months | Breast milk/formula + 100–200 ml water |
| 1–3 years | 1 litre total fluids/day |
| 4–8 years | 1.2–1.5 litres total fluids/day |
| 9–13 years | 1.5–2 litres total fluids/day |
| 14+ years | 2–2.5 litres total fluids/day |
During Illness: When to Watch More Carefully
- Stomach flu / gastroenteritis — track every wet diaper and fluid intake
- Fever above 102°F (38.9°C) — increases fluid needs 10–15%
- Vomiting that lasts more than 6 hours
- Diarrhea with 4+ loose stools daily
- Hot summer days with outdoor play
Mistakes to Avoid
- Don’t give plain water alone for moderate dehydration — ORS is better.
- Don’t force-feed large amounts; small sips work better.
- Don’t use fruit juice as primary rehydration — worsens diarrhea.
- Don’t withhold food entirely — keep breastfeeding/feeding normal.
- Don’t use anti-diarrheal medicines on young children without a doctor.
FAQs Parents Ask Most
Q: How can I tell if my baby is dehydrated when they can’t talk?
A: Count wet diapers — fewer than 6 in 24 hours is a warning sign. Watch for sunken soft spot, no tears when crying, sunken eyes, and dry mouth. See a doctor immediately if you see any of these.
Q: Can I give my child coconut water for rehydration?
A: Yes, for children over 1 year with mild dehydration. It has good natural electrolytes. For moderate/severe dehydration, proper ORS is medically better.
Q: How quickly should I act if I notice dehydration signs?
A: Mild signs (thirsty, slightly dry lips) — start fluids immediately. Moderate signs (no tears, sunken eyes, reduced urine) — start ORS and see a doctor same day. Severe signs (lethargy, no urine 8+ hours) — emergency room without delay.
Q: Are sports drinks like Gatorade okay for sick kids?
A: No. They have the wrong electrolyte balance and too much sugar for sick children. They can worsen diarrhea. Use proper ORS instead.
