The worst is when it happens in the car. The smell gets in to everything, and you can guarantee that getting every last remnant of the vomit out of that car seat is impossible, no matter how many times you wash the cover, it finds its way into nooks and crevices that you never even knew existed.
On more than one occasion I have contemplated trading our car in on another one just to get rid of the smell...
Its lasted that long? There was one time that she was about to throw up in the car, but I got my jumped and caught most of it in my hands before it went everywhere... maybe it was a good decision after all!
