(HealthDay News) -- There may be warning signs before your child has a full-blown asthma attack.

The American Lung Association says parents should be on the lookout for these potential red flags that an asthma attack may be imminent:

• A frightened facial expression and posture that indicates the child can't relax.
• Restless sleep.
• Coughing, particularly at night.
• Sweating, pale skin, rapid breathing and flaring of the nostrils.
• Labored breathing with the lips pursed.
• Vomiting and fatigue.
• Sunken areas between the ribs or in the neck.
