Cold and cough in children are usually caused by viral infections and often improve on their own within a week. There is no single best medicine that cures a common cold. Treatment mainly focuses on relieving symptoms and keeping the child comfortable. For fever or body pain, paracetamol can be used at the correct dose based on the child's age and weight. Saline nose drops can help clear a blocked nose. Warm fluids and plenty of rest are important. For children over 1 year old, a small amount of honey may help reduce coughing. Avoid over-the-counter cough syrups unless advised by a doctor, especially in young children, as they may not be safe or effective. Please seek medical help if your child has difficulty breathing, a high fever lasting more than a few days, poor feeding, or worsening symptoms.
