  1. Bold fonts indicate p < 0.05
  2. 1Due to distribution, AIMS stand was dichotomised based on median as a dummy variable (value = 1 [score = 2, reference group]; value = 0 [score > 2])
  3. Results are pooled for all imputation data sets. Covariates (AIMS assessment: infant age; Baseline: infant sex, infant race/ethnicity, number of siblings, parental age, parental marital status, parental education, parental country of birth; Average across time points: non-parental care time) were included in all models. Mean imputation was performed for missing parental age at baseline (n = 1)
