The investigators will address the hypothesis in the following Specific Aims:
Specific Aim 1: Validate ultrasound as a method to measure whole body fat mass and fat-free mass in toddlers. Body composition will be assessed using ultrasound measurements and the validated method of air displacement plethysmography (ADP).
Specific Aim 2: Determine the effect of a handheld Force-Measuring Ultrasound Probe on intra- and inter-observer variability in ultrasound measurements. A device which measures the force applied to the ultrasound probe will be used to obtain measurements of muscle and adipose tissue thickness (biceps, abdomen, and quadriceps) in toddlers.

Ultrasound, ADP, bioimpedance measurements |
- Ultrasound Measurements [ Time Frame: through study completion, up to 2 years ]Tissue thickness (adipose and muscle) will be measured in cm using the ultrasound probe.
- Body Composition Measurements [ Time Frame: through study completion, up to 2 years ]Fat and fat-free mass will be measured in kilograms using bioimpedance and air displacement plethysmography.
- Neurodevelopmental Status for 2 year olds [ Time Frame: through study completion, up to 2 years ]Bayley Scales of Neurodevelopment III will be used to measure neurodevelopmental status at 2 years of age, including cognition, language, and motor scores (composite scoring for each area: Cognitive, 55-145; Language, 47-153; Motor, 46-154).
- Neurodevelopmental Status for 3 and 4 year olds [ Time Frame: through study completion, up to 2 years ]Weschler Preschool and Primary Scale of Intelligence (WPPSI) at 3 and 4 years of age will be used to measure neurodevelopmental status for toddlers 3, 4, or 5 years of age. Quotient and Composite scores have a mean of 100 and a standard deviation of 15. Subtest scaled scores have a mean of 10 and a standard deviation of 3.
