Calorie Deficiency, Calorie Overload
Conditions
Brief summary
The investigators have created and validated a device that allows us to accurately measure how many calories a baby consumes every day. The purpose of this study is to compare how many calories a baby consumes with how many calories are provided in a population of newborn infants and children. This may help clinicians to better understand how to feed babies during times of critical illness.
Interventions
