With a baby that sensitive, I'd be looking at doing Elimination Communication. It would also help you see if her urine looks like a UTI -- cloudy, discolored, strong, like deep yellow instead of nearly clear.
EC has it's own forum over in diapering.
Little girls do not like to be wet! My little girl certainly didn't like it. She likes to be clean and dry.
She wakes up at night to say, I'm wet. Soon, very soon, I hope she'll be waking up before the I'm wet. I did a 1/2 effort on EC. If I were so lazy, she probably be using the potty now.
