Since your child is otherwise active, feeding well and has predominantly night-time cough after a viral illness, the common causes are post-viral cough, allergy, or cough-variant asthma. A physical examination by a pediatrician is important. Blood tests are not routinely required. If the cough has persisted beyond 4 weeks, your pediatrician may consider a chest X-ray and assess for allergy/asthma. Seek urgent care if breathing difficulty, persistent fever, wheezing, vomiting with cough, or poor feeding develops.
