Oh dear, i feel for you, i think the best thing you can do is wash everything up, and make sure people wash their hands before they eat and after they use the bathroom, and if you really want to make sure try making some sort of bleach solution and spray the things that could be risky, wash cups, cutlery etc and wash most things your daughter touches for about 2-3 days, mainly cups and cutlery, then you should be fine.
i know it sounds like a lot to do but that's the problem with noro :-/
good luck!
