What treatment would a 7 month old child get for skinniness and failure to thrive?

Find the cause. The primary approach to ftt is an investigation to uncover a cause. Analysis of caloric intake, food preparation, pattern of growth, signs of excessive energy loss, etc, all come into the evaluation. A detailed history, exam & a few screening tests usually find a source. Treatment is based on cause.The most common factor is nutrition, followed by illness or genetic issues.
