Sooo sick of sickness

I wanna know something! How in the world can 3 kids stay sick for an entire winter when they are never even out? Seriously, it isn't like I get them out of the house & parade them around the town. For Heaven's sake, we are basically hermits. But this winter has sucked! I don't think they all have been healthy at the same time. Someone always has something. And then that someone usually passes it on to the other two & it becomes nothing but a big, nasty, vicious hell of a cycle.

Ahhhhhhhhhh, when will Spring get here?
