Aww, poor little one Maybe take it day by day. See how she is by the end of the weekend and then make your decision? If she's still really unwell, give it a miss, if she's doing better, see how she's doing on Monday and go from there?

I know you guys live a long way away, but that's how I worked it with a friend of mine who lives about the same distance away a few weeks back. She was meant to come see me on the weekend. On Monday, she told me she was vomiting and having a really bad time, did I still want to keep our weekend plans. I asked her to text me how she was doing on Thursday and she was much better, she was meant to be coming on Friday, but she just ended up coming over on Saturday and staying til monday instead of sunday instead.
