This is exactly what my husband and I think, which explains why there is some element of truth to his statement about the monitors and the precious angel being blue (gosh I hate typing that
).
He already
knew she was blue -- I doubt it was perfectly clear on the monitor.
However the scenario played out, we think SW went in to check on them & when she saw her babies lying there lifeless, she did what I have done in that situation...grab the child/person & shake her to get a reaction, which he was calmly viewing in the monitor and is SIMILAR to strangling so that image is fixed firmly in his mind as an explanation to what happened (sounds crazy when I think about it now but it was an automatic reaction...and obviously the child I was shaking had not been murdered, just choking on a small piece of candy).
Then he went in and strangled SW while she was distracted
All MOO of course
