We hear from Sierra Leone, where the 2 Young Lives project supports teenagers who've been rejected by their families for getting pregnant. They link them up with older women who step in to look after them.

Complications during pregnancy and childbirth are a leading cause of death for 15–19-year-old girls globally. But the mentors are making sure the young mums get the medical support they need.

After giving birth, the early years of motherhood can be problematic for teenagers too.

We also hear from Brazil, where a team of researchers and nurses is teaching young mothers the skills they need to form strong attachments to their children.

By getting their mothers to do things like read to their toddlers, the researchers say they can improve the children's future development and give them better life prospects.
