Laoyao is the nickname of the elders for the youngest child, so there is no specific ranking, as long as it is the last one. For example, a family has three brothers, and Lao Yao is the third and seventh brother, so it is Lao Qi and so on.
The most precious "only son (female)", "old Yao" and the most neglected "second child" in the family.
Does the birth order between brothers and sisters affect the parent-child relationship? We further divide non-only children (people with brothers and sisters) into three categories:
The eldest son, this category refers to those who rank first in the family and only have younger brothers or sisters.
Middleborns, this category refers not only to the second child in the family, but also to those groups with both brothers and sisters.
In English literature, they are usually called "middle class". They can also rank "third" or "fourth". There are no proper nouns to call them in Chinese, so they are collectively called "second child" here.
Lastborns, this category refers to those groups that rank last in the family and only have brothers or sisters.
This classification shows that the oldest and youngest children may come from families with two children or from extended families with three or more children. The second child can only come from large families with three or more children. Therefore, when we analyze the influence of sibling ranking, we can eliminate the interference caused by the total number of children by controlling the total number of children in the family.
We found that in the family, the relationship between the only child and his parents is closer than that between the eldest child and the second child in the family with many children. Compared with the old family with many children, the advantage of the only child has disappeared, and it is even "inferior" to the old family to some extent.
