My DS has just turned two, but I'm struggling to get him to play outside to make the most of the warm weather. He loves going to the park/playground, but if I take some of his toys out into our garden he gets upset and drags them back inside again.
We've got an open plan living room with french doors out onto the patio and garden, and he prefers to sit in the living room on his own and play with his cars or trains rather than play with me in the garden. He's got a sand and water table, play tent and tunnel, a trike etc but will only play with them outside for a few minutes at the most.
