It did with DS. I thought it was over and it was 5 or 6 hours later he started again. It was a strange bug here though he came good for a couple of days eating and drinking normally seeming fine, then he ended up being a bit off again. No more vomits but a few dodgy poos. Took a good week to clear completely.
Keep her fluids up, water water water! If you get worried take her to the doctor for a check.
