My 2yr DS has had bad gastro bug for nearly a week now on and off and he has been throwing up yellowish/greenish bile and is very tired and sleeps more then usual. I've sat at hospital for 5-6hrs and all he did was spew and sleep which the Dr said was fine (sleeping that is), so just get some hydralyte from the chemist (don't freeze it) and use a eyedropper and give her 2-3mls every 10-15mins, that's what I got told anyway.

Hope she gets better soon.
