We have tied a basket on a piece of rope and ds has hung it out of the bedroom window. I am down below (on sofa) and have a stash of things next to me which I am putting into the basket (out of the window) when he lowers it down. He then pulls it up and shrieks with delight.
So far I have put snacks, a letter with his name on and a drawing of us inside, a recorder, some stickers and a notebook, some playmobil people, etc etc etc
the apple came a cropper, but otherwise all is well and he is SO EXCITED and keeps shouting "Thank you mummy oh thank you!"
