my baby is 5 months old.he is having cold and running nose. we took him to doctor.he gave mucolite,otravin pediatric drops and atrax syrup . he told to give calpol if he is crying severe.since he might have eat pain. If I start giving calpol should I continue the course for 3 or 5 days or should I give him when he crying too much only.he doesn't have any fever. should I give calpol or not ???
