Though many ethnohistoric sources in the tropical Pacific recount chiefly feasting events, few describe childhood feeding practices despite the impact childhood under-nutrition may have had on morbidity and early mortality. Bioarchaeological investigation of the Namu burial ground (circa 750–300 BP) on the island of Taumako (southeast Solomon Islands) provides a direct means of understanding prehistoric life on a Polynesian Outlier in the south western Pacific. We investigate infant and childhood (0–10 years) feeding behavior in prehistoric Taumako by creating δ¹³C_collagen, δ¹⁵N_collagen, and δ¹³C_carbonate profiles from 20 individuals using horizontal dentin sections of permanent first molars. The high-resolution data created using novel sample preparation offers insight into childhood diet in the absence of documentary evidence, incrementally sampling δ¹³C_collagen and δ¹⁵N_collagen but also expanding on the method to provide carbonate data from the same sequential dentin samples.

The individuals who died in adolescence have significantly lower δ¹⁵N_collagen values in early life than those who died in adulthood, which may suggest a link between diet, nutritional health, and morbidity. There were no significant differences in isotope values between social status groups, suggesting shared childhood experiences regarding types of foods consumed. Longitudinal assessment of δ¹³C_collagen and δ¹⁵N_collagen shows a strong relationship between the two values, likely a result of the typical tropical Pacific diet consisting largely of high protein marine foods that overshadows low protein terrestrial foods. This highlights the utility of δ¹³C_carbonate in order to more effectively investigate consumption of low protein foodtypes in this region.

尽管热带太平洋地区的许多民族史资料主要以节食事件为依据，但尽管儿童期营养不良可能对发病率和早期死亡率产生影响，但很少有人描述儿童期的喂养方式。对Taumako岛（所罗门群岛南部）的Namu墓地（大约750-300 BP）进行生物考古学调查，为了解西南太平洋的波利尼西亚离群前的史前生活提供了直接的手段。我们通过创建δ调查婴儿和儿童（0-10岁）摄食行为在史前Taumako ¹³ Ç_胶原蛋白，δ ¹⁵ ñ_胶原蛋白，δ ¹³ C ^_碳酸盐使用永久性第一磨牙的水平牙本质切片从20个人获得的轮廓。使用在没有单据新颖样品制备报价洞察童年饮食，增量取样δ高分辨率数据创建¹³ Ç_胶原和δ ¹⁵ Ñ_胶原而且扩大对方法从同顺序的牙本质样品提供碳酸数据。
