The Duchess – along with her husband the Duke of Cambridge - began the day (Friday, March 27) with a visit to the Stephen Lawrence Centre in Deptford, south London, set up in memory of the teenager murdered by a racist gang in 1993.
Stephen's mother Doreen, Baroness Lawrence of Clarendon, accompanied the royal couple on a tour of the building, which was opened in 2008 as a centre of excellence for architecture and design.
Stephen, 18, had wanted to become an architect and the centre helps other young people to realise similar ambitions. It also hosts programmes in IT, creative arts and multi-media.
Kate's due date is in April, though the exact date remains a secret. The only clue she has given was during a visit in mid-March, when she told a volunteer: "I'm due mid-April, to the end of April. Not long to go now."
It means the royal baby could share the same birthday as the Queen, who will be 89 on April 21, or her or she could arrive on the Duke and Duchess's fourth wedding anniversary, April 29.
After visiting the Stephen Lawrence Centre, the Duke and Duchess were scheduled to travel a few miles to Gypsy Hill, to see the work of the Excel Project (XLP), a charity working to help young people from inner London boroughs to have a bright future.
The Christian charity is based at Christ Church, but helps young people of all faiths and none.
It began after Patrick Regan, a church-based youth worker, was asked by a local headmaster to come into his school and help children with behavioural issues following a stabbing in the playground.
