Water and usual fluids
For many children, water, breast milk, formula, or their usual milk can help maintain hydration. Older children may do well with frequent small drinks rather than large amounts at once.
Help Your Child Stay Hydrated During a Fever
If your child has a fever and is drinking less than usual, it can be hard to know what fluids to offer, how much is enough, and when dehydration may be a concern. Get clear, parent-friendly guidance based on your child’s current drinking and symptoms.

About this assessment
Answer a few questions for personalized hydration guidance
Share how well your child is drinking right now, and we’ll help you understand practical hydration tips, fluids that may help, and signs that mean it’s time to seek medical care.
01
Why hydration matters when a child has a fever
Fever can increase fluid loss and make some children less interested in drinking. That combination can raise the risk of dehydration, especially in babies, toddlers, and children who are also vomiting, breathing fast, or sleeping more than usual. The goal is not perfect drinking all at once. Small, steady sips and the right fluids can often make a big difference.
02
Best fluids for fever in kids
Oral rehydration solutions
If your child is drinking much less than usual or losing fluids from sweating, vomiting, or diarrhea, an oral rehydration solution may help replace both fluids and electrolytes.
Cold, soothing options
Ice chips, popsicles, chilled water, or diluted fluids may be easier to take when a sore throat or general discomfort makes drinking harder.
03
Hydration tips for a child with fever
Offer small amounts often
A few sips every 5 to 10 minutes can be more manageable than asking your child to finish a full cup.
Use familiar cups and routines
A favorite cup, straw, spoon, or syringe can help, especially for toddlers who are resisting fluids.
Watch output, not just intake
How often your child urinates, whether their mouth looks moist, and how alert they seem can give helpful clues about hydration.
04
Signs of dehydration during fever in children
Mild to moderate signs
Dry lips, less frequent urination, darker urine, fewer tears, and drinking less than usual can all suggest your child needs more fluids.
More concerning signs
Very sleepy behavior, dizziness, sunken eyes, a very dry mouth, or barely drinking anything may mean dehydration is becoming more serious.
When to seek care promptly
Get medical advice sooner if your child is refusing all fluids, has not urinated for many hours, seems hard to wake, or you are worried they are getting worse.
05
How much should a child drink with a fever?
There is no single amount that fits every child because needs vary by age, size, activity, and whether other symptoms are present. A useful approach is to focus on steady intake and signs that hydration is being maintained, such as regular urination, a moist mouth, and improving energy. If your child is drinking much less than usual, personalized guidance can help you decide what to try next.

Frequently asked questions
What should I give my toddler to drink with a fever?
Start with small, frequent amounts of fluids your toddler usually accepts, such as water, milk, or an oral rehydration solution if intake is low. Cold fluids, popsicles, or spoonfuls of liquid may be easier than a full cup.
Are electrolytes helpful for a child with fever?
They can be helpful when a child is not drinking well or is also losing fluids through vomiting or diarrhea. Oral rehydration solutions are generally preferred over sports drinks because they are designed for children’s hydration needs.
When should I worry about dehydration with fever?
Be more concerned if your child is barely drinking, refusing all fluids, urinating much less, has a very dry mouth, seems unusually sleepy, or is difficult to wake. If you notice these signs, contact a healthcare professional.
How can I prevent dehydration when my child has a fever?
Offer fluids early and often, use small sips if larger drinks are refused, and keep checking for wet diapers or bathroom trips. Children often do better with frequent reminders and easy-to-drink options within reach.
