Final answer:
The RN explains that keeping the nipple full of formula during bottle feeding helps prevent the baby from swallowing air, reducing the risk of colic and discomfort.
Step-by-step explanation:
Ensuring the nipple remains filled with formula serves a crucial purpose in bottle feeding. When the nipple is kept full, it minimizes the intake of air by the baby, reducing the likelihood of colic and discomfort. Swallowing excessive air during feeding can lead to gassiness and fussiness in infants.
The nurse's advice aligns with best practices in bottle feeding, emphasizing the importance of proper techniques to create a comfortable and efficient feeding experience for the baby. This guidance can contribute to the well-being of both the baby and the mother, fostering a positive feeding routine.
