DD kindly gave us all her bug which I suspect is full blown Noro given the symptoms. Vomiting, stomach cramps, muscle aches etc.
I have lucozade sport to rehydrate and am currently munching an ice lolly during an ok spell.
There are cans of coke in the fridge too but any other suggestions welcome especislly since DD is now feeling fine and all the rest of us are having to deal with a toddler whilst feeling like death.
