What principle is reflected when a nurse shows a mother how to let her baby squeeze her finger?

The situation described illustrates the principle of attachment behavior being stimulated by maternal signals. When the nurse shows the mother how to let her baby squeeze her finger, she is facilitating a moment that fosters bonding between the mother and the infant. This tactile interaction promotes the establishment of a secure attachment, which is crucial for the baby's emotional development and well-being.

This behavior also highlights the importance of maternal responsiveness in enhancing attachment. The mother’s engagement through physical touch and eye contact while the baby experiences this grasping can deepen the emotional connection and encourage the baby to feel safe and loved. Such interactions are vital during the early stages of development as they contribute to the formation of strong, healthy attachments, which are foundational for the child's overall growth and future relationships.

Other principles present in the choices do not capture the essence of the interaction as effectively. Neonates indeed exhibit reflexes and behaviors such as grasping, but the focus on active maternal interaction and response showcases the power of these bonding moments rather than merely stating a reflex action.
