my baby is 3m old he was heavy cough then what I do

A. A heavy cough in a 3-month-old baby needs careful attention, as babies this young have delicate respiratory systems. If the cough is severe, persistent, or accompanied by breathing difficulty, fever, or refusal to feed, consult a doctor immediately. Home Remedies for Mild Cough in a 3-Month-Old (⚠️ Do not give honey or any herbal remedies at this age) Breastfeeding More Frequently – Breast milk helps boost immunity and soothe the throat. Steam Therapy – Sit in a steamy bathroom with your baby for 10–15 minutes. The moisture helps loosen mucus. Saline Nasal Drops – If there is nasal congestion, use saline drops (like Nasivion Saline) to clear the nose. Hold Baby Upright – Keeping your baby slightly elevated during feeds and naps can help with congestion. Gentle Chest Massage – Warm mustard oil with a little ajwain (carom seeds), strain it, and apply lightly on the baby’s chest, back, and soles of feet. Avoid Cold Air Exposure – Keep the baby warm but not overheated. When to See a Doctor Immediately ❗ Difficulty breathing (nostrils flaring, chest pulling in). ❗ Continuous cough for more than 3 days. ❗ Wheezing or whistling sound while breathing. ❗ High fever (above 100.4°F). ❗ Poor feeding or excessive sleepiness. If the cough is persistent, a doctor may check for viral infections, bronchiolitis, or reflux-related cough. Let me know if there are any other symptoms, and I can guide you better!
