I just wanted to give you my two-cents for clearing the diaper rash. Give her a baking soda bath. Add 1/2 to 1 cup of baking soda to her bath water and give it a swish to dissolve it. My daughter's pediatrician recommended this when my dauthter had diaper rash so bad that it was beginning to bleed. I was amazed with the releif she got. She could be crying in pain and would stop the instant her little bum hit the water. The bright blister red would be almost gone when she was done with the bath.
Kindest regards and Best of luck. I've had a sick baby though the holidays and it is the worst.
