Around 2am I finally succumbed. Same symptoms as everyone else. I wasn't able to sleep too much through the night, and felt pretty terrible.
Grandpa really came through though, and dropped by in the morning, staying 'till late afternoon, handling both kiddies and letting Madeleine and I get some much needed rest.
By the time he showed up in the morning we were both pretty near the end of our ropes, I don't know how we can begin to repay him for his help.
As of now, it seems like the worst is past. Still upset tummies, no real appetites to be found in the house, but noone is throwing up anymore.
