Synchronized Sleeping??

I am proposing a new Olympic sport...
only because my children seem to have an innate talent for it...
Synchronized Sleeping!
Observe...

Averie & Evan share a double bed & let me assure you (though it may be hard to believe) that there has been absolutely NO "posing" done for this picture. We checked in on them before we went to bed & they were just sleeping away like this! What is even stranger is it is not the first or last time it has happened!! (Just the only time we were "with it" enough to grab the camera).

Is it possible that there is a genetic component to preferred SLEEP POSITIONS?? I never would have thought it before... but the evidence seems to be piling up around our house! LOL
