A nurse is providing teaching to the parent of an infant who has gastroesophageal reflux. Which of the following statements by the parent indicates an understanding of the teaching?

A. "My baby's formula can be thickened with oatmeal." While some infants with reflux may benefit from thickening their formula, oatmeal is not typically recommended as a thickening agent. Parents should follow specific medical guidance on safe thickening agents for formula. B. "I will keep my baby in an upright position after feedings." This statement demonstrates an understanding of appropriate management of gastroesophageal reflux (GER). Keeping the baby upright after feeding helps prevent the backflow of stomach contents into the esophagus, reducing reflux symptoms. C. "I will have to feed my baby formula rather than breast milk." This statement is incorrect. Breast milk is not contraindicated for infants with GER, and in fact, breast milk may be easier to digest and may help reduce reflux symptoms compared to formula. D. "I should position my baby side-lying during sleep." This statement is not recommended. Babies should be placed on their back for sleep, as side-lying positions can increase the risk of sudden infant death syndrome (SIDS). The back sleep position is safest for all infants, including those with reflux.
