Answer: frightening, unpredictable, or excessive
Explanation: Discipline should steer clear of qualities such as being scary, erratic, or over-the-top. Fear or intimidation must not be employed as it can adversely impact a child's emotional health and have long-lasting harmful effects. It is also crucial to avoid unpredictability or extreme harshness in discipline, as these can hinder a child's growth and harm the relationship between the parent and child. Instead, discipline should be well-structured, predictable, and reasonable while also being fair, kind, and respectful. To promote a positive and supportive environment for children to learn and develop, it's beneficial to incorporate qualities like honesty, empathy, and generosity.
