In my experience kids that age tend to focus on one or two things they aren't supposed to do & put all their energy into doing that. Opening & shutting the camper door until they slam their fingers or get bumped off the step by someone coming out- all my kids.
Oh that steep embankment that everyone else goes down but they aren't allowed near- run fast as you can towards it every chance you get.
DeOrr was a normal little boy, rambunctious & learning limits. He SHOULD have been misbehaving, squirting the mustard into the dirt, getting into things & driving my everyone nutty.
There is no description provided by anyone to indicate that he was a lively, regular two year old on this camping trip.
I am beginning to wonder about the drive from Idaho Falls to Leadore. Was he napping? Jabbering? Screeching the whole time? The more I think about this the more concerned I become that these parents not only participated in their child's death, have actively covered it up, but may have also passed his deceased or significantly ill body off as a sleeping baby.
You bring up some really good points in your post. Normally when discussing & remembering about a child and all the funny things they have done and all their little things that are forming their character can be a very sore point if you have a deceased child. Initially from my own personal experience of losing an adult child it was a long time before i could even talk about the really good memories of him. What was first & foremost in my mind was the shock of his sudden death.
I don't know with JM & VDK and it depends on what they know & are thinking happened to Deorr. Even if Deorr had a fatal accident and are covering that up, and they are not monsters as some of the parents that have caused their child to disappear they would still have to be grieving to an extent IMO.
