What are non-normative crises?

Non-normative crises refer to unpredictable life events that significantly impact individuals or families but do not typically occur in every relationship or life scenario. These events can be traumatic experiences such as sudden illness, job loss, death of a family member, or any other crisis that is not part of the expected developmental stages.

In contrast, the other options describe events or situations that are more common or regular occurrences within family dynamics. For instance, life events that happen in every marriage or stages that all families experience in their lifecycle align more with normative aspects, which are expected and often planned for. Common issues faced during parenting also fall under typical challenges that families anticipate and prepare for as part of raising children. Thus, the characteristics of non-normative crises center around their unpredictability and unique, individual nature, which is why this answer is correct.
