A nurse is reinforcing teaching about bottle feeding techniques with the guardian of a newborn. Which of the following statements by the guardian indicates an understanding of the teaching?

A. "The feeding should last 5 to 10 minutes.": Newborn feedings usually take 20 to 30 minutes, depending on the baby’s sucking strength and tolerance. A 5–10 minute feeding is typically too short for adequate intake. B. "My baby should be burped prior to feeding.": Burping is recommended during and after feeding, not before. Burping helps release swallowed air and reduce discomfort, so this statement shows a misunderstanding. C. "My baby might spit up a small amount of formula while feeding.": It is normal for newborns to regurgitate small amounts of formula due to an immature lower esophageal sphincter and active feeding. Recognizing this as typical demonstrates correct understanding of bottle-feeding expectations. D. "The opening of the nipple should be enlarged.": The nipple hole should be appropriately sized to allow slow, controlled flow of formula. Enlarging the opening can cause choking, gagging, or overfeeding.
