Ds (age 9) has been throwing up since midnight. It was every hour but has been every half hour since early this afternoon. He's thrown up 22 times so far.
He's had tiny sips of rehydration liquid which come back up, we also stopped liquids to see if that would stop him being sick but it didn't work. He has wee'ed today, last time was early this afternoon. His skin still springs back, he has tears and he is awake and ok, just feeling very sorry for himself. He is vomiting liquid and foamy stuff, with tiny bits of brown streaks (but not 'coffee grounds').
How long do we give it before we worry? DH is less concerned than I.
