Sorry I have run into a snag in the known facts about where Madeleine was actually sleeping and so I am having to research that and then I will have to rethink some of my conclusions. I had based some of my earlier thoughts on the alleged fact that Madeleine had slept on the same bed (all the children together) and inbetween the twins but that apparently has turned out to be incorrect.
This pic alleges to show the sleeping arrangements for the children.

And this news article seems to agree with the picture (picture came from a different news place the daily mail.)
" . . .The other children, two-year-old twins Amelie and Shaun, were still asleep in their cots. . ."

So now I am rethinking some things that were based on that "in the middle" sleeping position which now seems to be very doubtful.
Soon as I have some things straight in my head I will post more on the subject but itmay take me awhile to let things percolate. Something about all that is on the edge of my thoughts and I need time to pluck that nagging almostthought out of thin air and hope it isn't something silly when I finally get it.
