Key Points:

• To diagnose with Faltering Growth (aka Failure to thrive): the infant must fall below weight-for-age or weight-for-length percentile or have rate of weight gain decline across 2 major percentiles.
• There are three categories to think about when evaluating the etiology of faltering growth:
• insufficient calories in
• malabsorption or increased calories out
• increased metabolic requirement
