I think I mentioned before, but it took us a solid 2-3 days before DS would hold down anything but pedialyte, so try not to let that worry you that she got sick again (easier said than done, of course). When I got the bug the next day and the thought of eating anything made my stomach flip-flop, it was actually a nice reminder -- that not eating real meals for a couple of days in the course of sickness is normal and not cause for alarm on its own.
