Overnight Parenting & Early Childhood
Research on overnight parenting in early childhood explores how overnight time away from a primary caregiver relates to attachment and early development. Many studies focus on infants and toddlers and examine whether the timing and frequency of overnights are linked to later measures of attachment or adjustment.
​
The findings in this area are mixed and continue to be debated. Researchers generally note that overnight arrangements do not operate on their own and that broader caregiving context matters. As a result, the literature emphasizes developmental stage and family circumstances rather than one-size-fits-all conclusions.
Overnight Parenting Arrangements and Attachment in Infants and Toddlers
Tornello, S. L., Emery, R. E., Rowen, J., Potter, D., Ocker, B., & Xu, Y. (2013). Journal of Marriage and Family.
This national study examined how different overnight parenting schedules relate to attachment indicators and behavior among very young children. The findings show that infants in families with frequent overnights sometimes showed higher rates of insecure attachment to mothers, but toddlers did not show these same patterns, and no long-term behavioral problems were linked to overnights..

-
Infants experiencing frequent overnights showed higher rates of insecure attachment to mothers in some cases.
-
Toddlers did not show the same pattern, suggesting age-related differences.
-
Overnights were not linked with long-term emotional or behavioral problems.
-
Parenting conflict and instability may explain more risk than overnights themselves.
Parental Separation and Overnight Care of Young Children
Pruett, M. K. (2014). Oregon State Family Law Advisory Committee Materials.
This practitioner-oriented review summarizes research on overnights and caregiving for infants, toddlers, and older children in separated families. Drawing on attachment theory, it emphasizes that infants experience far less stress during separations when they have access to another effective attachment figure. When both parents are responsive caregivers, overnights can help maintain these essential bonds with minimal distress. The paper outlines conditions that support healthy transitions and offers practical guidelines for developmentally appropriate parenting plans.
-
Attachment theory shows that infants experience much less distress during separations when another effective attachment figure is present. When two secure caregivers are available, stress is reduced and transitions become easier.
-
Children benefit from regular, predictable contact with both parents, including overnights when caregiving is stable.
-
Transition stress is driven more by parental conflict or inconsistency than by overnights themselves.
-
Flexible, developmentally informed schedules help children adjust at all ages, not just infancy.
-
Parenting plans should be tailored to the child’s temperament, history with each parent, and the level of cooperation between caregivers.
Social Science and Parenting Plans for Young Children: A Consensus Report
Warshak, R. A. (2014). Psychology, Public Policy, and Law.
This expert consensus report—endorsed by 110 leading child-development researchers—reviews the scientific literature on parenting plans, overnights, and caregiver involvement for infants, toddlers, and young children. The authors conclude that maintaining frequent, meaningful contact with both parents supports secure attachment and healthy development, and that blanket age-based restrictions on overnights are not supported by evidence.
-
Young children can form secure attachments to both parents when caregiving is stable and sensitive.
-
Overnights can support healthy bonds, provided both homes offer predictable routines and emotional availability.
-
Age-based bans on overnights are not supported by the broader body of research.
-
Parental conflict and instability—not overnights themselves—pose the greater developmental risk.
