The first few years of life are critical for cognitive development. Parents can boost that development with simple interactions. Dost helps illiterate moms build skills to get their kids ready to succeed in school and life. They create and deliver short, engaging ‘phonecasts’ with tips and activities to build brains and give kids a needed head start. It’s an easy and fun way for illiterate parents to help their kids learn “school readiness”skills (pre-numeracy, pre-literacy, social, emotional, and self-regulation). The inherent scalability of Dost's technology makes it a potential solution for families from the slums of Delhi to rural Rajasthan.
