How Much Fluid Does My Child Need?

Children lose fluid faster than adults, so the goal is to replace every loss as it happens. The World Health Organization's guidance for oral rehydration solution (ORS) after each loose stool is roughly:

AgeORS after each loose stool
Under 2 years50–100 ml (a quarter to half a cup)
2–10 years100–200 ml (half to one cup)
Over 10 yearsAs much as they want, like an adult

If your child vomits, wait 10 minutes and start again more slowly — a teaspoon every 1–2 minutes. Keep breastfeeding or formula feeding as usual. ORS sachets (called oralit) are sold in every pharmacy (apotek) in Bali.

How Dehydrated Is My Child?

MildModerate — call a doctorSevere — urgent care
Playful, drinking normally, passing urineIrritable, very thirsty, dry mouth, fewer wet nappiesDrowsy or floppy, sunken eyes, no tears, no urine for 8+ hours, cold hands and feet

Medicines: What to Avoid

When a Doctor Visit Helps

A doctor can check hydration, look for other causes such as ear or urinary infection, and decide whether your child needs anti-nausea medicine, a stool or blood test, or IV fluids. Our doctors see children at hotels and villas across Bali, usually arriving within 30–60 minutes in the main tourist areas. Babies under 6 months, children who are very drowsy, or those with blood in the stool should be seen urgently — go to a hospital emergency department if you cannot get a doctor quickly.
