Most experts now believe that asthma develops in an individual within the first few years of life. These symptoms sometimes can be observed during infancy, but there are other cases where asthma does not make its presence known until later in childhood or even into adulthood.

Signs of childhood asthma differ depending on the age of the patient. Signs in infants may include:

• Noisy breathing
• Breathing increases to more than 40 breaths per minute during sleep
• Feeding or suckling ceases
• Chest size appears to expand
• Nostrils flare
• Skin is pulled tight between an infant’s ribs
• Face turns pale or red; fingernails turn bluish
• Grunting
• Lethargy or decrease in responsiveness
• Lack of interest in normal or favorite activities
• Frequent respiratory infections
• Changes in the sound of the child's cry (e.g., softer than usual)

Children with asthma may exhibit several signs of the disease, or may suffer through just one symptom, such as a chronic cough. Signs and symptoms of asthma in children may include:

• Regular coughing
• Chest pain or tightness
• Less energy while playing
• Shortness of breath
• Rapid breathing
• Chin or throat itchiness
• Dark circles beneath the eyes
• Wheezing
• Frequent respiratory infections
• Lack of interest in normal or favorite activities

It is important to note that coughing related to asthma will often occur at night or during sleep, after vigorous physical activity (e.g., running) and with emotional outbursts (e.g., laughing, crying).

Parents with children who are experiencing any of the signs or symptoms of asthma should consult a physician.
