It's awful isn't it? My DD had a particularly nasty one around this time last year and unfortunately you do just have to wait it out. I think it took a good 7-8 days to be fully out of my DD's system. I'd also hold off on the milk for now and make sure she is regularly sipping water or even some very watered down juice. The hydralite icypoles are great for littlies too. I hope you are all better soon hun, there are some nasty bugs out there
