A child may cough after getting warm in bed due to overly dry indoor air or an upper respiratory tract infection. If the cough is caused by dry indoor air, you can improve ventilation by opening windows or use a humidifier to adjust indoor humidity. If it's due to an upper respiratory tract infection, the child can take medications such as Cefixime Granules under a doctor's guidance. However, please note thatCefixime Granulesare recommended for children over 6 months of age.
