my daughter is 3 years old and she is having dry cough

A. Use a cool mist humidifier. Drink warm fluids. Warm fluids can feel soothing if your child's throat is sore from coughing. If your child is at least a year old, you can add some honey for added relief.Also called a hacking cough; if it persists after a cold, it likely is caused by residual mucus that will eventually clear up. If a kid's dry cough happens mostly at night, your child could have asthma. Mucus in inflamed and narrowed lung passages causes irritation that creates a cough.
