Something I found a bit odd - not evidence to convict, but odd - the mother put that baby to bed wearing shorts and a shirt, not a gown or nighty, but shorts - it was 56 degrees overnight.
I sleep in shorts when it’s 55 degrees overnight.
That is odd, but I confess that I sometimes used to put my daughter into her crib for the night in her shorts or other playclothes if she had fallen asleep in them, rather than wake her up.
