Is there anyway to take the cover off the AOE? My friend's little boy is rear-facing in it (NOT my choice of a seat) and threw up all over the cover. They can't get the cover off for anything... I think that should be a sign to trash the seat and get a better one. My friend says she hates the seat with a passion and wishes she would have gotten something better, and admits she fell victim to the "only seat you'll ever need!!!"
