House Arrest and Early Childhood: An Initiative to Support Young Children's Development

There is a reality that is not widespread but deserves greater attention: young children living with a parent or caregiver serving a sentence under house arrest. This judicial measure allows individuals to serve their sentence at home rather than in prison, helping children maintain the daily care of their mother or father. However, on its own, it does not ensure the conditions children need to thrive. In practice, government oversight tends to focus on compliance with the judicial measure, while children's developmental needs, caregiving environment, and access to essential services often remain overlooked.

We know that the early years of life are a critical period for child development. Evidence consistently shows that interventions during this stage—especially in highly vulnerable settings such as those experienced by these children—are among the most cost-effective investments governments can make. The question, then, is how to use this opportunity to reach these families at the right time and support young children's development.

In the city of Buenos Aires, with support from the Inter-American Development Bank (IDB), a pilot program was designed to address precisely this challenge. 

Currently in its pilot phase, the program aims to promote the holistic development of children living with a parent or caregiver under house arrest. It combines three core components: 

• promoting early childhood development, 
• strengthening parenting practices, and 
• fostering coordination among the justice, health, and social protection systems.

The program adapts the Reach Up model, a parenting intervention originally developed in Jamaica that has been widely validated through international evidence. Based on home visits and structured play and interaction activities, Reach Up strengthens the capacity of parents and caregivers to support children's cognitive, language, and socio-emotional development during the early years.

The adaptation implemented in Buenos Aires applies this evidence-based model to a particularly challenging setting: households facing multiple forms of vulnerability, including social exclusion, institutional isolation, and an ongoing criminal justice measure. It also incorporates close coordination among the institutions that work with these families.

Across Latin America and the Caribbean, where an estimated 18 million children under the age of five are at risk of not reaching their developmental potential, parenting support programs have proven to be among the most effective interventions for improving early childhood development. Through structured, play-based sessions, they help parents and caregivers: 

• improve the quality of interactions with their children;
• foster language development and cognitive skills; and
• strengthen secure emotional bonds that support learning and well-being.

The evidence is clear: these interventions produce significant improvements in child development within the first months of implementation, and their benefits can last well into adulthood. 

One of the main challenges of this pilot has been adapting a proven model to a reality that differs substantially from the context for which it was originally designed. The intervention takes place in households where a judicial measure is in effect, support networks are often limited, and institutional coordination is inherently more complex.

For this reason, the program was designed through close collaboration among public agencies, specialized technical teams, actors within the justice system, and the IDB. This process made it possible to adapt key elements of the model—including home visits, play materials, and the support approach—to the specific characteristics of this context while preserving the components that underpin its effectiveness.

The pilot also includes an explicit link to the social protection system, enabling the early identification of potential rights violations and facilitating families' access to the services they need. 

Although initiatives like this are often viewed primarily through the lens of child protection, their potential extends much further. Evidence suggests that intervening early in these caregiving environments can help reduce risk factors associated with future pathways of exclusion, violence, and involvement with the criminal justice system. Programs like this not only improve children's developmental outcomes today but may also serve as tools for breaking cycles of disadvantage across generations.

Investing in the early years—particularly in highly vulnerable contexts—helps strengthen caregivers' capacities, improve the quality of children's home environments, and reduce inequalities that would otherwise tend to widen over time.
