When we examined the correlation between the residuals (after correcting for pathogen effects) of family‐level infection rate, we found a marginally significant positive correlation between 1 and 8 months of age (correlation coef. = 0.342, t = 1.993, df = 30, p = 0.0554; Figure 4a ), but no significant correlation between 1 and 10 months, (correlation coef. = −0.593, t = 1.4726, df = 4, p = 0.215; Figure 4b ), or between 8 and 10 months (correlation coef. = 0.485, t = 1.5669, df = 8, p = 0.156; Figure 4c ).
