Is it safe to leave a baby in the room while walking in the hallway?

Leaving a baby alone in a room, even for a brief moment, is not considered safe. Infants and young children are vulnerable and can easily find themselves in dangerous situations if left unattended. They may roll, crawl, or engage in activities that could lead to potential harm, such as pulling on objects or falling. Caregivers are responsible for ensuring a child's safety at all times, and leaving a baby alone—even in a seemingly secure environment—poses an unnecessary risk.

The other options suggest scenarios where leaving the baby alone might be considered, such as if the baby is sleeping or for a short time. However, safety standards emphasize that infants should always be supervised, regardless of their activity or state. Thus, the focus on vigilant care underscores the importance of always keeping a close watch on young children for their overall safety and well-being.
