Aww hun, I would definately get some gastrolyte, I forgot this time around but will definately use them next time, just so I know that she is having something. Iz didn't really eat over the 2 days - a tiny bit of soft stuff and that's it and watered down milk. (2 a day) When Izzy had it last time she was very lethargic after throwing up and had a bit of a fever but it was just a 24 hour thing. We called Nurse On Call as well, they were great - asked heaps of questions and let us know whether to monitor her at home or to take her in to see a Dr. Is she on AB's for her ear infection hun? Could be a reaction or associated with that too, so I would be inclined to take her to your GP if it's open today or go to a clinic to get her checked out.
