What Should I Do When My Child Gets Sick?
A complete A to Z guide to common toddler illnesses, home care basics, and knowing when to call your pediatrician
At a Glance
- Most toddler illnesses are viral and self-limiting, but some symptoms need urgent care
- Fevers, colds, vomiting, and diarrhea are common—but how your child looks and behaves matters more than the number on the thermometer
- Track symptoms and recovery trends, not just single episodes
Common Toddler Illnesses
- Upper respiratory infections (colds): Runny nose, mild cough, and low-grade fever. Usually viral and resolve in 7–10 days
- Fever: Can accompany many infections. Use weight-based paracetamol only when child is uncomfortable, not just for number alone
- Stomach viruses: Vomiting or loose stools for 1–3 days. Dehydration is the main risk—monitor fluid intake and diaper output
- Hand, foot, and mouth disease: Fever, painful mouth sores, and rashes on hands/feet. Highly contagious but usually mild
- Roseola: High fever for 3–4 days, followed by a sudden rash once fever breaks—common in under-2s
- Croup: Barking cough, hoarseness, and noisy breathing—especially at night. Usually viral but may need steroid treatment
When to Call Your Pediatrician
- High fever > 39°C that lasts more than 3 days or recurs after resolving
- Difficulty breathing: Fast, labored, or noisy breathing—especially at rest
- Signs of dehydration: No urine for 8+ hours, dry lips, sunken eyes, or listlessness
- Persistent vomiting or severe diarrhea: Especially if child can’t keep down fluids
- Fever with rash, stiff neck, or seizure: Needs immediate evaluation
What to Keep at Home
- Digital thermometer, infant paracetamol (doctor-advised dose), oral rehydration salts, nasal saline spray or bulb syringe, and clean cool compresses
- Avoid cough or cold medications for children under 4—they’re not proven effective and may cause side effects
What to Do Next: Guidance for Parents
- Watch how your child eats, drinks, plays, and responds—not just the fever
- Keep your child home from daycare during fever, diarrhea, or persistent cough
- Call your pediatrician if you’re unsure about symptoms or your child’s behavior feels “off”
