[|Human|] Hi my son is 21 months old, and has a cough for the past 6 weeks. We did see a doctor a couple of weeks ago and she said his chest was clear. It is really affecting him sleeping, as he is constantly being woken up by his cough. Should i be worried? Nikki
[|AI|]  Thanks for asking. Cough at night is most probably allergic. If your child is breathing comfortably and his chest is clear (according to your doctor). Then you can just give a non-sedative anti-allergic like cetirizine at nighttime. It will controlled his cough.  Cough at night and early morning cough can be sign of babyhood asthma. Watch for sounds of whistling coming from his chest when he is coughing. Disturbed sleep for more than three nights a week should worry you. Consult a pediatric pulmonologist for this problem Be vigilant for signs of respiratory distress which are fast breathing, flaring movements of nostrils, breathing movements of chest wall which causes depression in area below the ribs and neck area breath sounds which resembles whistling if this is so take your child immediately to emergency room. For now just give anti-allergic and homer enemies of cough like honey and ginger tea. Good luck
