The goal of the Child Health and Development Project: Mississippi Thrive! is simple. Since brains grow rapidly during the earliest years, we provide information and resources to improve developmental health for children ages birth-5 years . One in six children experience developmental delays, but thankfully, identifying and addressing these delays early helps them have more successful outcomes. It’s why we’re creating a comprehensive system of early childhood screenings and interventions. When our children thrive, Mississippi Thrives!
