This study examines the differential availability of family and parenting resources to children depending on their birth planning status. The National Longitudinal Survey of Youth data were analyzed, 3,134 mothers and their 5,890 children (M = 7.1 years, range = 1 month-14.8 years), of whom 63% were intended at conception, 27% were mistimed, and 10% were unwanted. Fixed-effects models show that unwanted and mistimed children had fewer resources than intended siblings. Parents' emotional resources to older children decreased after the birth of a mistimed sibling. Findings suggest that cognitive and emotional resources are differentially available to children within a family depending on intention status and that unintended births lead to decreased parental resources for older children in the household.
本研究考察了根据生育计划状况，家庭和育儿资源对儿童的可获得性差异。分析了全国青年纵向调查数据，涉及3134名母亲及其5890名子女（平均年龄7.1岁，范围为1个月至14.8岁），其中63%为计划内受孕，27%为时机不当受孕，10%为意外受孕。固定效应模型显示，意外受孕和时机不当受孕的孩子比计划内受孕的兄弟姐妹获得的资源更少。在时机不当受孕的兄弟姐妹出生后，父母给予年长孩子的情感资源减少。研究结果表明，根据生育意愿状况，家庭中的儿童获得的认知和情感资源存在差异，意外生育会导致家庭中父母给予年长孩子的资源减少。
