Florencia Lopez Boo presented at the 2025 Inter-American Development Bank Regional Policy Dialogue: "Childhood, Innovation, Impact: Transforming Early Childhood Development in Latin America and the Caribbean (LAC)" in Mexico City.

More than 100 participants, including authorities from 17 LAC countries, donors, civil society, and academics.
Wonderful speakers and panelists such as Susan Walker, Mariano Bosch Mossi, Marta Rubio-Codina, Carolina Freire, Romina Tome, Alexandre Bagolle, Claudia Vazquez, Jorge Gaete, Filipa de Castro, Eunice Deras, Andrés Moya, among many others.
Tremendous master lecture by James Cairns.
And a first-class closure of the "Child Development Innovation Fund."

Not only was it motivating to discuss the challenges of Latin America in the coming years, it was also nice to catch up with the Haiti and Argentina teams whom we are working on border agendas, and to see so many dear friends and colleagues. Congratulations to the Pablo Ibarraran team and the Inter-American Development Bank for this unique space for reflection.

Delivering early-childhood programs at scale is a major policy challenge. One way to do so is by using existing public infrastructure. This paper experimentally assesses the short-term effects of a new government home-visiting program integrated into health-care services. The program changed the allocation of time for community health workers by asking them to carry out tasks related to early-childhood development. We find that access to the program has a positive but modest effect on home environment quality and no effect on child development or on children’s health status. Our results point to the importance of workload, supervision, and buy-in from delivery actors to enhance fidelity of interventions.

Gaps in child development by socio-economic status (SES) start early in life, are large and can increase inequalities later in life. We use recent national-level, cross-sectional and longitudinal data to examine inequalities in child development (namely, language, cognition and socio-emotional skills) of children 0–5 in five Latin American countries (Chile, Colombia, Mexico, Peru and Uruguay). In the cross-section analysis, we find statistically significant gaps with inequality patterns that widely differ across countries. For instance, gaps in language and cognition for Uruguay and Chile are much smaller than those for Colombia and Peru. When turning to the longitudinal data, average SES gaps are similar to those of the cross-section in language but differ substantially in cognition, mainly in Uruguay where they emerge as more unequal when cohort effects do not operate. Importantly, we also find that the ECD gaps found at early ages (0–5) still manifest 6–12 years later in almost all locations and realms in which we have measures of early child development, but they do not increase with age. Results are robust to using different measures of inequality (income and maternal education). Gaps are smaller but generally remain when adjusting for possible explanatory factors (e.g. family structure, parental education, geographic fixed effects). To reduce ECD inequality and promote equality in later life outcomes, policymakers should look to implementing evidence-based interventions at scale to improve developmental outcomes of the most disadvantaged children in society.

Florencia Lopez Boo had the honor of delivering a keynote on “Investing Better in Child Development Policies, ”sharing reflections on how we can improve the design and delivery of impactful programs at scale.

We were also proud to present our poster on hybrid modalities of parenting programs from Jamaica, highlighting how flexible, evidence-informed models can better support families. Special thanks to Susan Walker and Fahmida Tofail for the insightful discussions.

Delivering early-childhood programs at scale is a major policy challenge. One way to do so is by using existing public infrastructure. This paper experimentally assesses the short-term effects of a new government home-visiting program integrated into health-care services in Brazil. The program changed the allocation of time for community health workers by asking them to carry out tasks related to early-childhood development. We find that access to the program has a positive but modest effect on home environment quality and no effect on child development or on children’s health status.

Building on the evidence from the first paper in this Series highlighting the fundamental importance of healthy and nurturing environments for children's growth and development in the next 1000 days (ages 2–5 years), this paper summarises the benefits and costs of key strategies to support children's development in this age range. The next 1000 days build on the family-based and health-sector based interventions provided in the first 1000 days and require broader multisectoral programming. Interventions that have been shown to be particularly effective in this age range are the provision of early childhood care and education (ECCE), parenting interventions, and cash transfers. We show that a minimum package of 1 year of ECCE for all children would cost on average less than 0·15% of low-income and middle-income countries' current gross domestic product. The societal cost of not implementing this package at a national and global level (ie, the cost of inaction) is large, with an estimated forgone benefit of 8–19 times the cost of investing in ECCE. We discuss implications of the overall evidence presented in this Series for policy and practice, highlighting the potential of ECCE programming in the next 1000 days as an intervention itself, as well as a platform to deliver developmental screening, growth monitoring, and additional locally required interventions. Providing nurturing care during this period is crucial for maintaining and further boosting children's progress in the first 1000 days, and to allow children to reach optimal developmental trajectories from a socioecological life-course perspective.

This article is among the first to quantify the actual impact of pandemic-related closures on early child development, in this case, for a sample of young children in Chile, where school and childcare closures lasted for about a year. We use a unique data set collected face-to-face in December 2020, which includes child development indicators for general development, language development, socioemotional development, and executive function. We find adverse impacts on children in 2020 compared to children interviewed in 2017 in most development areas. In particular, 9 months after the start of the pandemic, we found a loss in language development of 0.25 SD.
