Best of luck with the transfusion.
The stomach bug has hit our house, too. My little girl (aged 3) came in to our bed at about 2am. After 2 hours of her thrashing about making odd noises, the wife went downstairs to sleep on the couch. 10 minutes later the wee lassie puked. Went everywhere, the bed, walls, even in my slippers on the floor. She's off nursery today (no surprise) but I do feel bad as she missed 3 days last week with the cold.
