Day 4 - and in the team go to Kibera, Africa's largest slum where nearly a million people live in an area less than three square miles. Joined by the BBC, the team went to Stara School in the heart of the slum.
Although some of the area now has limited electricity and piped water, there is no sewerage system. After visiting the children in their corrugated metal classrooms, kits were handed out to the 500 children (371 of whom are orphans and one in 10 children who were HIV+).
Thanks also to eight year old Thomas Charley to handed out pencils and crayons to the children at the school and to his Dad, Warrant Officer Wayne Charley for his driving skills, knowledge of Nairobi and energy in getting us to some very difficult places to reach.
