Abstract Daily lifestyle regularity is measured using the Social Rhythm Metric (SRM). We developed a Baby SRM, with 59 babies followed for ~ 13 years. Baby SRM score at age 1 month significantly predicted the child's school (K-9, 5 time points) anxiety level (more regular = less anxious), and may be mediated through sociability and directed-attention pathways.
