The New York Times has a lovely slide show in their One in 8 Million Series on a teen mom in Brooklyn. It provides a realistic portrait of what young motherhood looks and sounds like:
Elizabeth Cousins: The Teenage Mother
One resource that is listed at the end of the slide show is The Brooklyn Young Mothers Collective.
"The Brooklyn Young Mothers’ Collective provides disadvantaged young mothers with a comprehensive set of services focused on their educational attainment and social development to help them to become self-sufficient adults."
