Breastmilk is the BEST thing. Better than water - I definitely wouldn't be giving her juice - it's too acidic. Just BF her as much as she wants. Try to do little feeds...
Keep her temperature down by giving some panadol NOT ibuprofen as this can sometimes irritate their bellies...
Pale & cold is not an abnormal response prior to vomiting, even though it is a bit scary it's quite normal.
Keep track of her wet nappies - obviously she will be having less of them as she is vomiting. But we want to see a wet nappy every 4-6 hours. If she is no better by early evening I would pop her up to the hospital. It is very easy for babies to become dehydrated. There is a particularly nasty bug around our parts at the moment...
