Go Away Stomach Bug!

We've been on a roller coaster of vomitting and diarrhea this past week and are really looking forward to it being over.  Apparently there's a stomach virus going around her daycare but Esme seems the hardest hit.  We thought she was getting better last Sunday but she's been up and down since then.  I had to stop nursing her for a short while since it'd always make her puke afterwards.  We then limited her to 2-3 ounce bottles of pumped milk and it was agony to see her hungry little eyes when she'd finish.  We don't know the exact amount but she's lost quite a bit of weight too from this past week.  Her belly's not as round so we can fasten her diapers tighter, her ribs are more visible, and her face is even thinner.  So far she's been vomit free for 2 1/2 days but she's still got the loose poops.  We added a probiotic to her diet but the only effect we've seen so far is that it makes her poop smell like fermented dairy.  We'll be soooooooooooo happy when this illness is over!  Our washer has been continuously going on the sanitize cycle ever since this started cause there's so much more laundry.
