# Unveiling Key Factors in Child Development: From Breastfeeding to Teachers’ Care in Brazilian Early Childcare Centers

## TL;DR

This study compares child development outcomes in Brazilian public and private childcare centers, highlighting the impact of factors like teacher practices and breastfeeding.

## Contribution

The study identifies specific proximal and distal factors influencing child development in different childcare settings.

## Key findings

- Children in public ECCs showed higher cognitive and language development despite lower socioeconomic backgrounds.
- Breastfeeding duration explained 24% of the variance in cognitive development.
- Teacher practices and gross motor toys explained 41% of the variance in motor development.

## Abstract

This study aimed to compare cognitive, language, and motor development outcomes among children attending public and private Early Childcare Centers (ECCs), considering birth factors and family and daycare environments. Additionally, it examined the proximal and distal factors influencing children’s development. Cognitive, language, and motor skills were assessed in the children, along with evaluations of ECC quality, teacher practices, and knowledge of child development. Results indicated that children enrolled in public ECCs achieved higher scores in cognitive and language development, despite coming from families with lower socioeconomic status and having lower birth weights. They also benefited from longer periods of breastfeeding. Teachers in public ECCs demonstrated greater daily practices, providing enhanced movement opportunities for children. Private ECCs offered more suitable outdoor spaces, whereas public ECCs had better indoor spaces. Regression analysis revealed that daily practice, teachers’ experience, and the availability of gross motor toys explained 41% of the variance in motor development. The duration of breastfeeding explained 24% of the variance in cognitive development. Teachers’ knowledge about children’s development and attendance at public ECCs explained 31% of the variance in language development. These findings underscore the importance of prioritizing teacher education in both public and private ECCs to optimize children’s overall development.
