A nurse is reinforcing teaching with the parents of a 2-month-old infant who has gastroesophageal reflux. The parents are feeding the infant formula. Which of the following instructions should the nurse include in the teaching?

A. Change the infant's formula to a soy-based formula: Soy-based formulas are not routinely recommended for gastroesophageal reflux. Formula changes should only be made under the direction of a healthcare provider after evaluating for intolerance or allergy. B. Limit the infant's formula feedings to every 6 hr: Infants require frequent feedings, typically every 3 to 4 hours. Extending intervals can lead to inadequate nutrition and worsen irritability or reflux due to overfeeding during fewer sessions. C. Keep the infant at a 30° angle for 1 hr following each feeding: Maintaining the infant in an upright or semi-upright position after feeding helps reduce reflux episodes by promoting gastric emptying and minimizing regurgitation. D. Give the infant a bottle immediately before the infant's bedtime: Feeding right before lying flat can increase the risk of reflux during sleep. It's better to feed the infant slightly earlier and keep them upright afterward to reduce symptoms.
