I visited my eldest daughter today who's having problems with my two year granddaughter not sleeping at night. She's tried every trick and every bit of kidology in the book, to no avail. The latest thing is a 'Sun and Moon' device. It's set to a timer and if my granddaughter wakes in the middle of the night when the moon is shining, she should know that she should try to go back to sleep. If the sun is shining, then she is allowed to get up and go to mummy and daddy's bedroom. So today, while she was sitting on my knee, I ask my granddaughter what she does if she wakes up and the sun is shining. "I go to mummy and daddy's room and climb in to bed with them," she replied. "Then what do you do if the moon is shining?" I asked.
"Well," she replied, "I press the little button at the back to make the sun shine, and then I go to mummy and daddy's room."
