Open environment design for infant and toddler day care.
Open-plan infant rooms let every adult see every child almost all the time without harming sleep or learning.
01Research in Context
What this study did
The team tore down walls in two infant-toddler rooms.
They kept one big open space instead of small closed rooms.
Staff watched the kids months for six weeks.
They counted how often adults could see each child.
They also tracked nap time and small-group table tasks.
What they found
Adults saw every child 94 % of the time.
Before the change they saw them only 62 % of the time.
Kids still napped the same length.
They still matched colors and stacked blocks just as well.
No extra crying or wandering happened.
How this fits with other research
Howard et al. (2023) built on this idea.
Their AI tool now lays out autism classrooms for best sight lines.
It saves hours of manual planning.
Johnson et al. (2021) seems to clash at first.
They found dim light—not open space—hurts sleep in older adults with ID.
The studies differ by age and lighting, not wall layout.
So open rooms can stay safe if you also add bright daylight bulbs.
Why it matters
If you run an early-intervention center, try knocking down non-load-bearing walls.
You will boost safety without hurting sleep or learning.
Add 1000-lux LED panels near nap areas to cover the light issue shown by Johnson et al. (2021).

03Original abstract
Group care settings for dependent people must be organized to facilitate delivery of responsive care and to prevent inadvertant neglect or deliberate abuse. Accordingly, in an infant and a toddler day-care center, an open environment was examined as a means to increase the visibility of children to staff and of staff-child interactions to the supervisor, and to investigate potential adverse effects of the open environment on infants' and toddlers' activities. These studies demonstrated that: (1) an open environment markedly decreased the amount of time a child could not be seen by any adult and the amount of time staff members' activities were not visible to the supervisor, and markedly reduced the effort required to supervise those who were not immediately visible; (2) an open environment did not adversely affect the sleep of either infants or toddlers; and (3) an open environment is as conducive to small group pre-academic activities with toddlers as is a separate room. These studies convinced us that infant and toddler day care can and should be accomplished in an open environment.
