Final answer:
The strategy not used for assisting reluctant babies to feed is tempting the baby with a bottle, which can cause nipple confusion. Colostrum is most important for providing immunoglobulins that boost the newborn's immune system.
Step-by-step explanation:
The strategy that is NOT designed to assist reluctant babies with feeding is "tempt the baby with a bottle". Early contact and feeding techniques such as helping the mother position her baby, encouraging skin-to-skin contact, and helping the mother express some milk before feeding can all promote a positive breastfeeding experience and contribute to successful feeding. "Tempting the baby with a bottle" might cause nipple confusion, particularly in newborns, and is thus not recommended as an early strategy to assist with feeding difficulties.
Regarding the importance of colostrum, it is foremost valued for its role in boosting the newborn's immune system through the provision of immunoglobulins. Although colostrum does have nutritional benefits and satisfies the infant’s thirst and appetite to some extent, its primary purpose is to transfer critical immune defenses from mother to child.
