What Does Your Child’s Body Temperature Indicate About His or Her Health?

Quick Answer: What Temperature is Fever in Children?

Normal body temperature: 97°F to 99°F (36.1°C to 37.2°C)

Fever (bukhar): 100.4°F (38°C) or higher

A fever is NOT a disease itself - it’s your child’s body fighting an infection. In most cases, fever in children is harmless and resolves within 2-3 days. However, knowing when to worry and when to stay calm is crucial for every parent.

Reassurance: Most childhood fevers are caused by viral infections and go away on their own. Your child’s body is doing exactly what it should - fighting off germs!

FAQs

Q: Baby has 102°F fever - when should I give Calpol?

A: You can give Calpol now. For fever above 100.4°F with discomfort, paracetamol helps. Calculate dose by baby’s weight (10-15 mg/kg). If fever doesn’t reduce within 1-2 hours or returns quickly, consult a pediatrician.

Q: How much Calpol for my 5-month-old baby?

A: A typical 5-month-old weighs 6-7 kg. Give Calpol Drops 0.6 ml or Calpol Syrup (120mg/5ml) 2.5-3 ml. Can repeat every 4-6 hours, maximum 4 times in 24 hours.

Q: Baby has fever after vaccination - is it normal?

A: YES, completely normal! Vaccine fever usually appears within 24-48 hours and lasts 1-2 days. Give Calpol if baby seems uncomfortable. Only worry if fever exceeds 104°F or lasts beyond 3 days.

Q: Fever 102°F - what to do at home?

A: Give Calpol (dose by weight), light clothing, plenty of fluids, and rest. Do tepid sponging 30 minutes after medicine if fever is high. Most 102°F fevers respond well to home care. Consult doctor if fever persists beyond 48-72 hours.

Q: Should I use cold water for sponging?

A: NO! Never use cold water or ice. Use lukewarm/tepid water only. Cold water causes shivering, which actually INCREASES body temperature. Stop sponging if child shivers.

Q: Can I give Calpol and Meftal-P together?

A: You can alternate them (not together) for persistent high fever, but only under doctor’s guidance. Typical pattern: Calpol, then Meftal-P after 3-4 hours if fever returns. Always consult your pediatrician first.
