Children, staff and carers tucked into an enormous celebration cake decorated with balloons and relighting candles. The celebrations kicked off with a concert, Rumble in the Jungle, performed by around 300 children with the support of members of the Royal Philharmonic Orchestra, in front of a tropical backdrop created by Molly Kelly, an artist who works with under-fives in a scheme run by the Tate Britain gallery.
