Which observation by the nurse indicates a positive acquaintance behavior between siblings?

• A. The older sibling asks questions about the baby's toes and fingers.
• B. The older sibling ignores the baby.
• C. The older sibling complains about the baby's presence.
• D. The older sibling tries to take over the mother's feeding.

Answer: (A)

A positive acquaintance behavior is shown when the older sibling shows curiosity and wants to learn about the baby, such as asking questions about the baby's toes and fingers. This demonstrates engagement, a gentle interest, and a desire to connect with the infant, which supports bonding and inclusion in the family. It also helps the sibling begin to assume a caregiving role in a safe, age-appropriate way.

Ignoring the baby reflects disengagement and potential detachment, while complaining about the baby's presence signals negative feelings. Trying to take over the mother's feeding shows possessiveness and boundary issues that can disrupt calm interactions and family routines.
