Shock does funny things. Not saying it's like that episode of Eastenders where in shock she swapped her dead baby with another. But I was in a serious car crash when I was young and denied all knowledge of being it in at first.
Hope people's judgement is reserved until the full facts are clear. Terrible tradegy but there is the chance of natural death. It 's easy to jump to conclusion, but no-one in sound mind would kill a child surely?
