Baby... err... toddler stats

The 15m appt has passed and Colby continues to grow and develop well. She screamed and retreated to mom or dad's arms for a vast majority of the appointment. How exactly does one assess lung sounds and heart murmurs with a screaming child??? She claims that everything sounded good. Two shots later, Colby actually walked out happy to well, walk out. Stats: she is 75th percentile in weight and 98th percentile for height.
