Tan, sounds like a tummy bug hun. Oskar had one a few weeks ago and doc said it lasts anywhere from 48 to 72 hours. Gastrolyte and hydrolyte are both great to use if she can keep that down.

I can't believe that the chemist hadn't even heard of gastrolyte though... weird!!! They can give that to you without going to the doc too by the way. There are several different brands around but they're the main two names. If she still can't keep water down it may even warrant a trip to the ER so they can rehydrate her through a drip as that's the main thing to help her get better. Hope she gets better asap!!!

Oh and no dairy while she's still sick either, makes them vomit
