Asthma symptoms in children ages 5-11. Common asthma signs and symptoms in children ages 5 to 11 include: 1  Coughing, particularly at night. 2  Wheezing. 3  Difficulty breathing. 4  Chest pain, tightness or discomfort. 5  Avoiding or losing interest in sports or physical activities.
The wheezing is treated just like asthma, but it goes away by itself, usually by age 5 or 6. Most kids who have symptoms like wheezing and shortness of breath beyond that age are considered to have asthma, and they may always have it. But for about half of them, symptoms go away around adolescence.
