As was said above, it may be the drying effect she doesn't like. You could always apply cuticle oil around the finger, not the nail while soaking off so it creates a barrier.
The only way to remove them quickly is to use acetone, but you could always buff them off so they are really thin, being careful not to reach the natural nail, then oil the fingers and skin surrounding the nails and briefly soak them in acetone to take off the last layer. As it's thin, it won't take long. ( the buffing will though.)
