Why does a child's cough get worse at night, during sleep, in the morning or in the evening?
Applies to age: 0–60 months
In short
A cough that lasts a long time, especially when it gets worse at night, may be a sign of asthma, and it is worth seeing a doctor about it. If the child has increased shortness of breath, call an emergency medical team (ZRM) on 112 (the emergency number in Poland) or 999 (the ambulance number in Poland).
