Abstract Introduction Emotional self-regulation (ESR) skills are vital for mental and physical health. There is growing evidence linking sleep to ESR in school-aged children, but associations toddlers remain unclear. The current study examined between toddlers’ duration behaviors ESR. Materials methods This utilized baseline data from 1358 (Mage=26±3.9mo) the Let’s Grow trial. Total was calculated by summing parent-reported average nighttime daytime nap duration. Sleep (bedtime routine, bedtime resistance, latency, night waking) were assessed using Children’s Habits Questionnaire Brief Infant Questionnaire.

Girls boys had similar scores. However, girls longer naps than (1.6h vs 1.4h, t=-3.5, p=0.0004). inversely associated (all p<0.01), that higher positively more problem poorer Conclusion Initial results suggest improving toddlers. Supporting parents improve their may help foster skills.
