A toddler with a fever who refuses to drink is one of the most stressful situations for parents. Fever increases fluid loss, and refusing fluids accelerates dehydration. Here’s how to handle it.
Quick answer: A feverish toddler needs extra fluids, not less. If they refuse to drink for 6-8 hours, show signs of dehydration (no tears, dry mouth, fewer wet diapers), or become lethargic, contact your pediatrician or seek care. Small, frequent sips are more effective than forcing large amounts.
Why Fever + Refusing Fluids Is Concerning
Every degree of fever above normal increases your child’s fluid needs:
- Fever increases fluid loss through sweating and increased breathing rate
- A 102°F fever can increase daily fluid needs by 10-15%
- A 104°F fever can increase fluid needs by 20-30%
- Sore throat or mouth sores (common with fever) make swallowing painful
- The combination of increased need + decreased intake creates a rapid dehydration risk
Dehydration Warning Signs
Track these signs in your toddler:
| Sign | Mild | Moderate | Severe (ER) |
|---|---|---|---|
| Wet diapers | Slightly fewer | 1-2 in 12 hours | None for 6+ hours |
| Tears | Present | Reduced | None |
| Mouth/lips | Slightly dry | Dry | Very dry, cracked |
| Behavior | Mildly fussy | Irritable | Lethargic, limp |
| Eyes | Normal | Slightly sunken | Sunken |
| Skin | Normal | Slow to spring back when pinched | Very slow to spring back |
If you see signs in the “Severe” column, go to the ER immediately. Your child may need IV fluids.
12 Tricks to Get a Sick Toddler to Drink
The small-and-frequent approach
Don’t offer a full cup and hope for the best. Instead:
- Syringe or medicine dropper — Offer 5-10 mL every few minutes. This bypasses refusal and adds up fast
- Popsicles — Frozen Pedialyte popsicles, fruit popsicles, or homemade ones. Most toddlers will accept these even when refusing drinks
- Ice chips — Let them crunch on small ice chips (for toddlers old enough to handle them safely)
- Jello/gelatin — Counts as fluid intake and feels like a treat
- Watermelon and grapes — High water content fruits
- Diluted juice — Half water, half juice can be more appealing than plain water
- Warm broth — Especially if they have a sore throat; warmth can be soothing
- New or special cup — Sometimes a different cup, straw, or water bottle makes the difference
- Let them “help” — Pour their own water, use a fun straw, drink from your cup
- Bath time sips — Some toddlers will drink while playing in a lukewarm bath
- Pedialyte in a bottle — For younger toddlers who still accept bottles when sick
- Frozen fruit slush — Blend ice with a little juice and fruit
What counts as “fluid”
Anything liquid counts — water, milk, juice, broth, popsicles, gelatin, fruit with high water content. Don’t be picky about what they drink when the priority is that they drink.
Fluid Targets by Age
| Age | Minimum daily intake when sick |
|---|---|
| 12-24 months | 32-40 oz (4-5 cups) |
| 2-3 years | 40-48 oz (5-6 cups) |
| 4-5 years | 48-56 oz (6-7 cups) |
These are rough targets. The best indicator is wet diapers — at least 4-6 wet diapers per day for toddlers, or urinating every 6-8 hours for potty-trained children.
When to Call Your Pediatrician
Contact your doctor if:
- Your toddler hasn’t urinated in 6-8 hours
- They have no tears when crying
- They’ve refused all fluids for more than 6 hours
- Fever is not responding to medication — see our high fever guide
- They’re vomiting everything they drink — see our vomiting guide
Two Days Without Eating: When It’s an Emergency
Parents often search “baby won’t eat or drink for two days with fever” — and for good reason. Two days of refusing all intake is a critical threshold.
Refusing food vs. refusing fluids — an important distinction:
- Refusing food only (but still drinking some fluids): Common during illness. Most toddlers eat less when sick. This alone is not an emergency as long as they are still getting fluids. They will make up calories when they recover.
- Refusing fluids (even if eating some food): More concerning. Fluids are essential during fever. Call your pediatrician if fluid refusal lasts more than 6-8 hours.
- Refusing both food AND fluids for 2 days: This is a medical situation. Call your pediatrician immediately or seek same-day evaluation. Your child likely needs assessment for dehydration and may need IV fluids.
Emergency signs after 2 days of poor intake:
- No urine output for 8+ hours
- No tears when crying
- Sunken fontanelle (soft spot) in babies
- Extreme lethargy or difficulty waking — see toddler lethargic with fever warning signs
- Rapid breathing or rapid heart rate
Is your child also vomiting? If your toddler is vomiting and unable to keep down fluids, the dehydration risk is even higher. Read our guide on toddler vomiting without fever and dehydration signs for specific guidance.
Medication Considerations
If your toddler is not drinking well:
- Avoid ibuprofen when dehydrated — it can stress the kidneys. Use acetaminophen instead
- Use our dosage calculator for correct amounts
- Suppository forms of acetaminophen are available if your child is vomiting and can’t keep oral medication down — ask your pharmacist or pediatrician

Frequently Asked Questions
My baby won’t eat or drink for two days and has a fever — what should I do?
A baby or toddler who has refused both food AND fluids for two full days with a fever needs medical evaluation. While decreased appetite during illness is normal, two days without any fluid intake creates serious dehydration risk. Call your pediatrician immediately or seek same-day care. Watch for no tears when crying, fewer than 2-3 wet diapers in 24 hours, sunken eyes, or lethargy — these are signs of significant dehydration requiring urgent care or ER evaluation.
My toddler is refusing food and water with a fever — is this an emergency?
Refusing food alone is common during illness and not necessarily an emergency. Refusing water and all other fluids is more concerning. If your toddler has refused ALL fluids for more than 6-8 hours with a fever, call your pediatrician. If they show signs of dehydration — no tears, dry mouth, lethargy, fewer wet diapers — seek immediate care. Try popsicles, syringe feeding small amounts, or frozen fruit slushes as alternatives to a cup.
Dehydration in toddlers can progress quickly, especially with fever. Monitor wet diapers closely and don’t hesitate to call your pediatrician. For structured guidance, use TriageNest.
