At first glance, this looks just like any other preschool. But most of the children here have been fighting tough battles with cancer. Seventy percent of them are now undergoing oncology treatment. Jolyn Phillipps is the brain behind Lion Hearts Learning, a playgroup she created to help her daughter. The kids can play and learn arts and crafts at the same time. It costs around 50,000 U.S. dollars a year to run the playgroup two days a week. The money is entirely provided by grants and donations.
