Except my 2yo is on day #4. There's one going around that has hit 4/6 of the family, myself included. Projectile out both ends (plowing and snowblowing on Sunday was interesting to say the least). We've seen posts and emails from friends around the country with the same thing. You're running out of time to get it over with by Christmas!
I'm still concerned that my DD and son#2 haven't shown signs yet and we're precariously close. We traditionally go to my grandmother's house on Christmas Eve but since she's undergoing dialysis we'll probably forego those festivities.

And we're hosting Christmas day dinner at our house. Not sure when to pull the plug on that, maybe give it another day to fester in the remaining healthy ones and see what happens.
I hope that none of you have to deal with it or at the very least it doesn't interfere with your plans. Wash your hands constantly!
