Which is NOT typically a change experienced by a family upon the arrival of a new child?

The arrival of a new child typically prompts numerous changes within a family system, with most adjustments aimed at integrating the new member into the existing family dynamics. The role of taking on parental responsibilities, realigning relationships with in-laws and older siblings, and developing peer relationships are all common experiences that families undergo.

However, the choice indicating a reduction in family size does not align with the typical changes expected when a new child is welcomed. In fact, the arrival of a new child increases the family size rather than decreasing it. Consequently, this choice accurately represents an option that does not fit with the other significant transitions families experience during this time, as families reorganize and adapt, rather than shrink in size.
