The practices and policies of a child care facility have an important effect on the health of children.

Stable, supported staff reduce illness transmission, improve supervision, and keep programs reliably open.

Improved indoor air ventilation and sanitation reduce infections.

Parents who ask questions strengthen expectations for health and safety across the child care sector.

Choosing a child care program is one of the most consequential decisions parents make during the early years of a child’s life. When my kids were young, I would visit classrooms, observe teachers interacting with children, and try to imagine whether it was a place that would keep my child happy and motivated to learn. I was also equally concerned, however, about whether the program had systems in place to protect my child’s health and safety.

Child care functions as both an educational setting and a health environment. Young children share toys, meals, air, and close contact with other children and adults, which means the policies, staff practices, and physical conditions of the facility shape daily well-being as well as the stability of the program itself. When health systems are weak, illnesses spread more easily, staffing becomes unpredictable, and programs may close unexpectedly. For parents who depend on reliable care so they can work, these child care disturbances can quickly disrupt the family’s life.

Most public discussion about child care focuses on affordability and the availability of seats. Those concerns are important, especially in the many communities in which the demand for child care greatly exceeds supply. At the same time, the experience of the COVID pandemic and several highly publicized safety incidents have reminded families that expanding capacity alone does not guarantee a system will be safe, trusted, and consistently open. Health readiness plays a central role in determining whether child care programs function smoothly over time.

Parents evaluating a child care program, therefore, benefit from considering three areas: how the program protects children’s health, how it supports the workforce responsible for daily care, and whether the building itself provides a healthy environment.

Is children’s health being protected in child care facilities?

Young children have developing immune systems and spend their days in close proximity to one another, conditions that make child care settings especially vulnerable to the spread of infectious diseases. Programs that operate smoothly over time treat infection prevention as a critical part of daily practice.

Vaccination policies provide one useful starting point. Most states require documentation that children are up to date on recommended immunizations before enrollment. Parents should confirm that these records are collected and maintained consistently, since high vaccination coverage helps protect the entire group of children in care.

Daily practices also reveal much about a program’s approach to health, including how teachers manage handwashing, diapering, toy cleaning, and food preparation. Teachers should also be able to explain the facility’s policies on when children should remain home because of illness and when they are allowed to return. These illness policies are an important part of preventing the spread of respiratory and gastrointestinal infections among young children.

Parents may also wish to ask how the program manages chronic health conditions, especially asthma, severe food allergies, seizure disorders, and diabetes. Facilities should maintain individualized care plans and ensure that staff are trained to recognize symptoms and respond appropriately when problems arise.

Child care programs are also an important setting for early recognition of developmental delays. Teachers who observe children daily may notice speech delays, hearing difficulties, or behavioral challenges. Programs that maintain connections with pediatricians or early intervention services can help families access evaluation and support during a developmental window when intervention is most effective.

Is the workforce's health being protected in child care facilities?

The adults who care for children have a large impact on a child’s education, emotional development, and health. When staff remain in their positions over time, children form stable relationships that support learning, emotional development, and a sense of security.

Parents can begin by asking how long teachers have worked at the program. High retention is a strong signal that the workplace is being well-treated.

The health of the workforce also affects the reliability of care. Child care workers experience frequent exposure to infections through close contact with young children. Access to paid sick leave and health care can determine whether staff feel able to stay home when ill or feel pressure to continue working despite symptoms, a situation that increases the likelihood that outbreaks will spread in a classroom.

Training represents another important component of workforce readiness. Staff should receive instruction in first aid, infection control, medication administration, and emergency procedures. These skills allow teachers to respond confidently during both routine health concerns and emergencies.

Does the physical environment promote health in child care facilities?

The physical environment of a child care program also plays a significant role in health and safety. Young children spend many hours indoors, which means that ventilation, sanitation, and building maintenance influence their well-being.

Better indoor air quality reduces the concentration of airborne viruses and allergens and may help promote brain development and functioning. Parents should ask whether classrooms have mechanical ventilation systems, portable air purifiers, and/or windows that can open for fresh air.

Facility design also affects routine health practices. Child-height sinks encourage handwashing, easily cleaned surfaces support sanitation, and well-maintained diapering areas help prevent infections. Outdoor play areas provide opportunities for physical activity and social interaction, both of which are important for health and development.

Parents may also ask whether programs monitor environmental hazards such as lead paint or mold, particularly in older buildings, and whether emergency plans exist for fires, severe weather, or other unexpected events.

Looking beyond the classroom

No child care program can eliminate every illness or accident. But the best programs integrate health protection into daily practices, support the adults responsible for caring for children, and maintain buildings designed to promote safety and well-being.

By asking informed questions about these issues, parents can gain a clearer understanding of what’s best for their child, and they can help spread the message that child care systems should protect health.
