Both of my older kids had this happen. My son got over it in weeks, but it lasted months for my daughter.
I know I've heard it happens to others, too. But I don't know the reason. We never changed products and the baths before the aversion were perfectly happy. I guessed it was just a phase. Toys and siblings in the bathtub helped make things fun again, but it certainly wasn't instant.
