Cot death is the sudden and unexpected death of a baby for no obvious reason.
The post-mortem examination may explain some deaths. No one knows yet why these babies die. Researchers think there are likely to be a number of different causes, or that a combination of factors affects a baby at a vulnerable stage of development. No, cot deaths can occur anywhere and at any time. Some babies die in their parents' arms or in a pram, but babies are usually found dead in their cots.
