The present study investigated whether the length of interbirth intervals between first and second-born children in a North-American middle-class sample could be explained by paternal and alloparental support and firstborn children's gender. The sample consisted of 225 families in which mothers were expecting their second child. Parents reported on paternal and alloparental support (maternal kin, paternal kin, and non-kin support). The results showed that higher maternal kin support and having a firstborn son was linked with shorter interbirth-intervals. Mothers' longer work hours during the pregnancy with the second born was related to longer interbirth intervals. These results highlight the importance of maternal kin support and children's characteristics in understanding the timing of birth when parents have a second child.
本研究调查了在北美中产阶级样本中，头胎和二胎之间的生育间隔长度是否可以由父亲及异亲支持以及头胎孩子的性别来解释。样本包括225个母亲怀有二胎的家庭。父母报告了父亲及异亲支持（母亲的亲属、父亲的亲属和非亲属支持）情况。结果显示，较高的母亲亲属支持以及头胎是儿子与较短的生育间隔有关。母亲在怀二胎期间工作时间较长与较长的生育间隔有关。这些结果凸显了母亲亲属支持和孩子特征在理解父母生育二胎时的生育时间方面的重要性。
