I think the worst is over. The Little Madam has been puke-free since yesterday morning and hasn't produced another foul-smelling poo since the one which interrupted yesterday's morning nap. Plus, she's replaced her recent behaviour of sleeping all night and napping lots during the day, with her more usual wakefulness. In fact, right at this very minute she's resisting my second attempt at getting her to take a morning nap. She's also laughing lots and shuffling about looking for trouble. The old TLM is back.
But I'm feeling a tiny bit of nausea, myself. Either I've caught what she had - which has a quite high probability - or I'm being paranoid.
