Parental separation and overnight care of young children, Part II: Putting theory into practice
Family Court Review
Report summary
How can attachment, development, and the future health of both parent–child relationships be translated into case-specific overnight planning?
Table 1 sets out eight considerations covering safety, relationships, parental mental health, child development and adjustment, coparenting, practical resources and family factors. The authors advised that higher-frequency overnights, defined in the table as five or more per month, were not generally indicated for infants aged 0 to 18 months even when the listed conditions were met. This is the authors' practice guidance, not a finding from a trial of schedules.
Key limitation: Practice framework rather than a primary study
Researchers' conclusions
The authors sought to protect early developmental security and both lifelong parent–child relationships rather than elevate either aim as an automatic trump.
This is a plain-language summary of the researchers' conclusion. It is not advice for an individual family.

How the report was produced
Important limitations
- Practice framework rather than a primary study
- Clinical assumptions require professional judgment
- A checklist cannot substitute for reliable case evidence
Evidence context and debate
Open the sections below for the wider research context, points of agreement, and areas that remain contested.
Editorial interpretation of the wider topic
This section discusses the wider topic. Its statements are not all findings of this individual paper.
Across later work, rigid age cut-offs have given way to more conditional frameworks based on established care, safety, conflict, transitions, and child characteristics.
These papers integrate research rather than randomly assign families to plans. Their recommendations must be separated from the underlying empirical findings.
Questions the wider evidence informs
- Making assumptions, evidence, and value judgments visible when moving from research to guidance.
- Individualizing plans around actual caregiving history and the child’s functioning.
- Protecting both developmental security and meaningful parent-child relationships where possible.
- Reviewing arrangements as children and family conditions change.
Limits of the wider evidence
- Presenting a professional framework as though it were a randomized trial.
- Using an age chart without examining the facts that the framework says matter.
- Treating either equal time or primary residence as scientifically mandatory in every ordinary case.
- Allowing a population-level recommendation to displace safety evidence in an individual family.
Why this question matters
Developmental research entered family-law guidance through attempts to translate attachment, separation, caregiving, and parental-involvement findings into practical schedules.
Parenting-plan papers sit at the boundary between science and recommendation. They draw on attachment, parental involvement, separation, sleep, conflict, and developmental research, but the plan itself is not usually tested through random assignment. A reader must therefore distinguish the empirical findings being cited from the authors’ professional synthesis of what those findings imply.
Kelly and Lamb emphasized developmental capacities and maintaining both relationships. Warshak argued that blanket restrictions undervalued father-child relationships and were not supported by direct evidence. McIntosh, Pruett, and Kelly’s companion papers integrated attachment and involvement while providing a structured set of child, relationship, and coparenting considerations.
Across these papers, the field has moved away from a single primary-parent formula. The remaining disagreement is less about whether both relationships matter and more about the prudent starting point, the pace of transitions, and how to respond when the evidence on a particular age or schedule is sparse.
Where researchers agree and disagree
There is substantial agreement that plans should be individualized and should protect children from harmful conflict, abuse, neglect, and abrupt loss of familiar care.
Authors differ over the preferred default when evidence is incomplete and over how quickly substantial overnight care should develop for very young children.
Comparison with other research
Kelly & Lamb, 2000
Used developmental research to support schedules that preserve both relationships while reflecting the child’s capacities and established care.
Warshak, 2014
Opposed blanket overnight restrictions and argued for maximizing both relationships in ordinary circumstances, with individualized exceptions.
Pruett, McIntosh & Kelly, 2014 Part I
Joined attachment and involvement perspectives through a triadic secure-base model and retained conditional caution.
McIntosh, Pruett & Kelly, 2014 Part II
Translated the integration into a practice framework covering the child, relationships, parenting capacity, safety, conflict, and transition demands.
How the evidence developed later
The literature increasingly states exceptions and boundary conditions explicitly.
Pruett, McIntosh and Kelly (2014) treated attachment and parental involvement as complementary.
Recent consensus warns courts that attachment science supplies principles, not an automatic schedule.
Policy evaluation is developing as a separate evidence stream from developmental guidance.
