We will not obtain labs to exclude children. If children are noted to have liver disease or renal disease in their chart, we will look at their labs to ensure that they do not meet exclusion criteria). * Children with tracheostomy and/or inspired oxygen via nasal cannula or children receiving diuretics. * Children with known or suspected genetic and/or metabolic inborn errors of metabolism conditions known to interfere with growth or body dysmorphology that can interfere with obtaining standard anthropometric measurements (weight, length, head circumference, and arm circumference) * At study entry, children expected to consume on average more than 20% of their energy intake from non-formula sources of nutrition: solids, expressed breast milk and /or parenteral nutrition. * Child requiring or expected to have an energy requirement \< 80 kcal/kg per day - Breastfeeding child (who is feeding at the breast \> 2 times per day) * Child likely to undergo major surgery during the duration of the study * Child with a nasogastric tube that is unlikely to get a gastrostomy tube during the duration of the study * Principal Investigator's uncertainty about the willingness or ability of the parent/caregiver to comply with the protocol requirements * Children whose parent is younger than the legal age of consent * Children with known allergy to pea protein or soy or peanuts. * Children with a parent or a sibling with a known allergy to pea protein or soy or peanuts.
