| The article is focused on the original Sub-mono-children aged from two to ten in Suzhou. Through sending self-created surveys and interviewing the original Sub-mono-children between the ages of two and five, researchers conducted the study on the acceptance of the second-born child among those sub-mono-children. The research is aimed to know the general situation of the respondents’ attitudes to second-born children. It analyzes the situations and differences in the attitudes that firstborn children, who are raised up in different environments, have towards the second-born child. The research is also designed to find out the factors that affect the acceptance of second-born children among the sub-mono-children and to come up with corresponding strategies to solve the problem. The ultimate purpose of the research is to provide some references and examples for creating a beneficial environment for the firstborn children to develop their mental health.The research shows that over half of the respondents have negative and rejecting attitudes to the second-born child in the family. Gender, age and the degree of familiarness are some of the factors that affect the sub-mono-children to accept the second-born child. Based on the study of several specific cases and relevant psychology theories, the article analyzes the factors that cause sub-mono-children to reject the second-born child from four aspects, which are objective aspects – family and society, and subjective aspects – the growth stage and attributional tendency of sub-mono-children.Finally, the article proposes some constructive suggestions on the acceptance of the second-born child among sub-mono-children in three perspectives, which are family, school and society, in order to help solve the problem that sub-mono-children refuse to accept the second-born child in the family. |
