If you search online for the title of the book there is a preview read on Amazon of the first few pages. I had a quick look and I am a bit dubious about the information. I tend to trust the SIDS and Kids Australia website because they do all the statistical analysis and work with families who experience this trauma. This is the response of SIDS and kids to the toxic gas theory which seems to be a theme in the book: http://www.sidsandkids.org/documents...nStatement.pdf
