I didn't say or imply that JBR stripped and changed her bed, that's a big job for a sleepy 6 yr old. But climbing shelves to get a fresh pull up would be normal.
I thought JBR's bed was soiled that a.m. and am unaware of any claims that someone washed her bedding during that night.
My point is that a 6 yr old who wakes up wet may change themselves and either get into someone elses dry bed, or grab a clean blanket and move to the floor or sofa. So it's entirely plausible that JBR was moving around after everyone else was asleep. And it's also possible that she wasn't and someone "helped" her.
But the fact that the pull ups were on a high shelf means nothing in and of itself.
I didn't say it did. The Pull-up package that was hanging out of the cabinet just coincidentally was the same cabinet where the Swiss Army knife had been hidden. which was found near JBR's body in the wine cellar and coincidentally above the countertop where the potato knife had been put down.
