The Serene Haven private school in central Kenya is giving teenage mothers and pregnant girls a second chance to finish their education. Many of the girls, between the ages of 13 and 19, were forced out of their local schools. In a normal year, about 13,000 pregnant girls are forced to stop going to school, government research shows. That is likely to increase this year. Aid groups say COVID-19 restrictions closed schools and led to an increase in teenage pregnancies and sexual abuse.
