The American Society for Parenteral and Enteral Nutrition recommends monitoring electrolyte balance, especially if increasing formula concentration or adding supplements 7, 6

The American Academy of Pediatrics recommends scheduling weight check within 48-72 hours to assess response to interventions 1, 4
