Coughing 2 year old child

Good morning, ma'am. Coughing can be the result of post-nasal drip, where the nose runs down the throat like a faucet. This could be a symptom of allergies. If this is the case, your child may want to try an anti-histamine such as Aerius or Claritin. Your pharmacist will be able to show you the product and advise you on the dose to take depending on your child's weight and condition. I also suggest Hydrasense to irrigate and clean the sinuses to prevent secretions from accumulating and flowing backwards. Just don't use it within 30 minutes before bedtime. Don't hesitate if you have any other questions!
