The nurse is helping a mother breast-feed her newborn. Which activity by the infant is the best indicator that effective attachment to the breast has occurred?

Choice A rationale Effective latching is indicated when the infant's mouth is wide open, covering not just the nipple but also a significant portion of the areola. This deep latch ensures the nipple is positioned far back in the infant's mouth near the junction of the hard and soft palate, allowing the tongue to compress the milk sinuses underneath the areola to efficiently extract milk and protect the nipple from trauma. Choice B rationale Loud clicking or sucking sounds usually suggest that the latch is shallow and the infant is sucking on the nipple itself or losing suction, which can lead to inefficient milk transfer and maternal nipple pain or damage. Effective sucking is typically described as quiet, rhythmic, and characterized by cheek movements, indicating deep attachment and successful milk extraction. Choice C rationale While vigorous sucking initially is normal as the infant stimulates the milk ejection reflex (let-down), the pattern should then transition to slower, deep, rhythmic sucks with observable pauses, reflecting the flow of milk. Stopping after only 5 minutes, especially followed by relaxation, may indicate fatigue, poor milk transfer, or insufficient stimulation. Choice D rationale The infant's tongue should be positioned underneath the nipple, extending over the lower gum to cup the breast tissue, which is essential for drawing the nipple and areola into the mouth and compressing the milk ducts for milk release. If the tongue is securely on the top of the nipple, it impedes effective milk extraction and can cause painful friction.
