Healthy sleep is critical for child development, yet disparities exist, with Latino children disproportionately affected by deficient sleep. Most of what is known about sleep ecology and interventions to improve sleep in young children is based on studies of primarily White, non-Latino, and economically-advantaged families. To ensure the effectiveness of interventions, it is important to understand the contribution of socioecological factors on sleep among toddlers in low-income Mexican American families. This study employed in-depth interviews with a purposeful sample of low-income Mexican American Spanish-speaking (n=10) and English-speaking mothers (n=10) of toddlers (18-34 months old). Interviews focused on daily sleep routines, perceptions of toddler sleep behaviors, and environmental contributors. Transcripts were coded by two investigators and analyzed using a content analytic approach. For sleep-related parenting practices, 70% of mothers reported late child bedtimes (≥9:00 pm), 75% reported room/bed sharing, and almost a third of children fell asleep at bedtime with a bottle or cup. Maternal beliefs about child sleep included concerns that child crying during the night might disturb neighbors or wake siblings, and child sleep quality improved when the child is not hungry. Contextual factors impacting sleep included schedules, neighbors, and siblings. Specifically, later weekday bedtimes were attributed to maternal (but not paternal) work schedules, while wake times were often a result of a sibling’s school schedule. Weekend bedtimes were commonly reported to be delayed for toddlers due to families watching movies. Noisy neighbors, in particular upstairs neighbors, were identified as disrupting children’s sleep. Siblings were identified as both facilitating sleep (e.g., helping with routines) and disrupting sleep (e.g., distracting child at nap time). Findings provide insights on socioecological factors and parental beliefs about sleep ecology in low-income Mexican American toddlers that have implications for the design of interventions to improve child sleep. For example, commonly used behavioral sleep interventions have children sleeping in their own room, or require some crying during the night. However, these approaches may not be a good fit or feasible for this population. To address sleep health disparities, further work is needed to understand socioecological factors that require inclusive adaptations to pediatric sleep interventions. R01HL163859
