My wife has raised an unfortunately quite reasonable question.

What about the kids and the mud, flooded tents etc etc. I went this year and it was amazing but with no wife or kids. What happens when the weather is not as good? Is it disasterous, or with reasonable precautions can it still be incredible. My son has a slight disability that causes him to quite easily lose his balance, I tend to have this image of him falling over face first in the mud and then tantrums, screaming etc.

Not really being able to clean him up and with that amazing power the young kids have of sucking the joy out of a fanstastic situation.
Personally, I would rather ignore 'reality' and just go with the flow but my missus is far more steeped in the sensible aspects of such an adventure. So, please - sock it me.
