Nasty Tummy Bug

Not sure if anyone else has undergone the pain and stresses of this bug but it's certainly doing it's rounds. Lot's of schools have been reduced to handful of child attendance and hospitals have been flooded with visits of the same kind! It's basically making children very poorly, off their food and high temps all round! I've been upto my eyes in it literally with my 3 and I'm dreading catching it but I fear it may have started as I'm getting grumblings down below!!!
