Rowan Tree and Red Thread

My daughter Rowan is in hospital. She's been suffering from a viral infection for just over 3 weeks and on Wednesday night started vomiting. The doctor we took her too at midnight was worried and had her admitted to St. Finbarrs' Children's Unit. The consultant there (as well as the registrar and some other specialist who's name or position I failed to catch) all have a faintly annoyed air with us, as it seems they can't pin down what's wrong with Rowan. She's stopped vomiting, which I'm grateful for, but she's still intermittently nausea, suffering from abdominal cramps and generally looking like a ghost. She hasn't got a fever and there's no other signs of a bacterial infection, so we're grateful for that at least. During the days she's up and down a lot, one minute laughing and much like her usual self, the next cranky and listless, only to be followed by clingy and more tummy pains.

I hope we get some idea soon of how long this is going to take to clear, if is a virus, or of what exactly is going on, if it isn't a virus. I hate seeing Rowan like this and I hate being unable to make her better.
