mandyfins, I like your niece went through the very same thing 29 years ago, it will take her time and she will always miss the angel she gave back to heaven, the main reason for the natural labor is so the body and hormones react as natural as possible a c-section is basically to hard on the body and takes longer to heal
Prayers to your niece and you, also to the daddy, they suffer too.
Love
Angie
