I posted over the weekend because dd had a high temp that I was struggling to get down and she had also been sick. We saw the out of hours doc who said she just had a virus.
Since, she has been totally herself during the day, temp back to normal, appetite fine, but each evening or night she has puked everything up, including what she had for lunch almost 12 hours previous. Last night she woke up at 2.30 and it was obvious she had been sick hours before as she had been sleeping in it and it was all dry in her hair and on her face, ( I had been unwell and went to bed at 9pm, I checked on her then and she was fine).
So it's just once a day but every day for the past 3 days, this evening I noticed it started with hiccups, then coughing then threw up everywhere.
I'm really struggling to keep her hydrated, we are trying to avoid milk just in case that may be the culprit, but her nappy this morning was almost empty. 
Anyone with similar experience please.
