Diagnosis

Your baby's doctor will do a complete physical exam to identify any possible causes for your baby's distress. The exam will include:

• Measuring your baby's height, weight and head circumference
• Listening to the heart, lungs and abdominal sounds
• Examining the limbs, fingers, toes, eyes, ears and genitals
• Assessing reaction to touch or movement
• Looking for signs of rash, inflammation, or other signs of infection or allergies

Lab tests, X-rays and other diagnostic tests aren't usually needed, but in unclear cases they help to exclude other conditions as possible causes.
