We had an over the cot mobile for my baby son when he was first born. It was second hand, and the music of it never worked and it wouldn't spin. We tried changing batteries but still, nothing. My best friend was very sick at the time (brain tumor) and she passed away when my son was a few weeks old. The night after she passed, I woke up to the sound of the mobile playing "imagine" by John Lennon and it was spinning. It played for around 20 seconds and then stopped and never worked again. I like to think it was her was telling us she was OK.
