I don't know why I never labelled my thermometers. My dumb sleep deprived brain probably just assumed I'd remember which was which. Things are always so hectic when they're ill. Then it's over and you put everything away -until it's sickness-stress time again and you realize you haven't the foggiest which is which! Once we were past the "sticking stuff up their butts" stage of parenting (that's a milestone and a half!) I threw all the thermometers away to make ABSOLUTELY sure.
The big change while making this comic was removing the speech bubble in the last panel. It wasn't until right at the end that realized her face was already doing the job!
