Sickness Do Loop

What exactly is a Do Loop? Here's what Wikipedia had to say:
In most computer programming languages, a do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given boolean condition at the end of the block.

So I'm not sure if "do loop" works in this application, but I'm going to try... We have entered another sickness "do loop" at our house.  Here's how this bug went:
1. Claire gets sick
2. Ross gets sick
3. Gigi gets sick
4. Pop Pop gets sick
Everyone is better except baby girl because babies take twice as long to get over the yuckies and we thinking we're finally in the clear and then...
5. Momma gets sick

Ugg. I'm not sure who made up the saying "If momma ain't happy, ain't nobody happy" but I'd argue this saying is neck and neck... "If baby ain't happy, ain't nobody happy"!!!
