Last week, Kate, 37, hinted that Louis was walking, saying at a special exhibition in Bletchley Park that he was "keeping them on their toes". George, Charlotte and Louis have helped their mum to collect moss, leaves and twigs to decorate the garden, which uses hazel sticks gathered by the family to make its den. A swing seat, which Kate, Charlotte and Louis were photographed having a go on, hangs below the tree house. Kate designed the woodland setting along with award-winning landscape architects Andrée Davies and Adam White of Davies White Landscape Architects.
