I don't think of myself this way, I do think of this every night when it comes to my girls. I always wonder "is tonight going to be the night they wake up throwing up?", and I'm anxious about it all night if I wake up. My littlest did wake up throwing up a week and a half ago - she caught the sv her sister had 4 days previous. It sucked, but it's over, and hopefully now that they've had it twice in three months, maybe they won't get it again for a long time. Fingers crossed. I didn't catch it the second time, and when I caught it the first time I didn't vomit.
