Which of the following is a potential impact of poor bonding and attachment?

Poor bonding and attachment can significantly affect emotional and behavioral regulation in both the parent and the child. Dysregulated sensitivity and responses refer to the inability to properly interpret or respond to emotional cues from others, which can result from inadequate bonding experiences. This can lead to challenges in understanding and meeting the child's emotional needs, potentially affecting the child's development and the parent-child relationship.

In contrast, the other options imply positive outcomes that are generally associated with good bonding and attachment. Increased social support, enhanced partner communication, and improved maternal confidence are all benefits that typically arise when there is a strong, healthy attachment between a parent and child, as well as within the family unit. Therefore, the correct choice accurately reflects the negative consequences of poor bonding, highlighting how it can lead to a breakdown in emotional regulation and responsiveness.
