My only other comment, even if they only vomit once, check on them in the night, and give a dose of cortef and maybe some juice. Both of my SW kids got into "trouble" when I did not do this. It is now my policy if they are sick/vomit even once or fever, to dose them at 1:00 or 2:00 AM and even give a sweet drink. Both of my boys have been in a hypoglycemic state in AM when I did not do this, you would think I would figure it out the first time, anyway just something to think about. It has worked for us.
