Final answer:
Hand expression is preferred in the first 24 hours postpartum to reduce the risk of nipple confusion and to facilitate the flow of colostrum, which boosts the newborn's immune system.
Step-by-step explanation:
The question 'Why is hand expression preferred in the first 24 postpartum?' pertains to breastfeeding practices immediately after childbirth. Within this period, hand expression of breast milk is often recommended because it helps to reduce the risk of nipple confusion. When an infant is introduced to alternate feeding methods too early, such as bottles or pacifiers, they may develop a preference for those nipples over the breast, which can complicate breastfeeding. Hand expression allows the baby to feed directly from the breast, promoting proper latch-on and sucking techniques from the start.
Furthermore, the act of hand expression is beneficial as it can aid in the flow of colostrum, the highly nutritious first milk rich in immunoglobulins, which are essential for boosting the newborn's immune system. In addition, efficient expression and emptying of the breast can support the ongoing production of breast milk and help prevent potential issues such as engorgement or mastitis.
