Parents of an only child can devote more individual attention and resources to that child. They may have more time and energy to invest in their childs needs, education, and activities. On the other hand, parents with multiple children may need to divide their attention and resources, which can lead to less one-on-one time with each child. For an only child, their relationship with their parents may be more intense and centered around the parents expectations, as no other siblings can share that focus. Children with siblings, on the other hand, might experience a wider range of relationships, including sibling rivalry, cooperation, and shared experiences.
