Wow, I also never heard of this phobia. But I guess there is a phobia for everything if you think about it.
It's a good thing I don't have a problem with vomit (not that I like it or anything). Working with children for 12 years, I would have never made it. In fact, I had a baby that acid reflux. He would throw up after eating all the time if he didn't get his meds at the exact time he should.
I worked with a girl that couldn't even stand to wipe a childs nose. Then she got pregnant and I was like - oh dear, how are you going to manage? But as someone else stated, it was all fine with her own child.

So does this book teach you how to deal with it? Or is it just a book of other peoples stories who suffer from the same thing? (Sorry, I didn't look at the link.)
