It's always something

Last night I had a bit of deja vu. It was 10 p.m., Liam had been in bed for an hour, and suddenly there was wailing in his room. Both Chad and I beat a fast path to his door... opened it to find him in bed, not wedged between the bed and the wall... but wait... something isn't quite right? It took a moment to figure out, but rather than lying lengthwise on the bed with his flat sheet on top of him, Liam had somehow crawled, widthwise, underneath the fitted sheet on his mattress - it is a little loose on his bed. (Don't ask me how, or when, he did this - when I tucked him in, everything was normal.) So he had the fitted sheet on top of him, and beneath him was the waterproof sheet we keep on his bed in case there are any accidents. In other words... solid plastic. The elastic on the fitted sheet was tight enough that he couldn't find his own way out of it, and because he'd been sleeping on a plastic sheet for an hour on a hot summer night, he was completely soaked with sweat.

A change of pajamas and return to the proper lengthwise position fixed things relatively quickly. This morning, of course, he has no recollection of it. What on earth was he thinking?
