It's been 3 days since the last incident. And while I may be tempting fate by saying this, I believe the war is over.
CLAIRE HAS NOT BEEN SICK IN 3 DAYS!
Side Note: Claire just saw the midwife and heard the baby's heart beat for the first time! :D
UPDATE: Claire was sick on the 4th day that week, and then once a week for the next two weeks. Since then it's been very rare that she feels so bad she's sick, so while I may have been a little premature in writing this original post, we are now in a vomit free zone :) Mostly!
