I can tell you that it is entirely possible for people's feelings and desires regarding having children to change over time.
Many factors can influence a person's decision about whether or not to have children, including personal circumstances, relationships, career goals, financial stability, and emotional readiness. Someone who previously expressed a lack of interest in having children may undergo changes in their life or mindset that lead them to reconsider and eventually decide to start a family.
Conversely, some people who initially wanted to have children might change their minds as they experience life's challenges or gain a better understanding of their own preferences and priorities.
Human emotions and life situations are complex and can evolve over time. It's essential to respect people's choices regarding family planning and not impose judgments or expectations on their decisions. Each individual's journey is unique, and it's essential to support and understand each other as we navigate through life's changes.
