You did nothing wrong. You stood up as a strong woman, wanting to do what was best for her newborn son. The doctor's work for you. You pay their salary, they owe you an explanation whenever you think one is needed. They are in your employ, not the other way around.
So often we forget this whenever it comes to medical and healthcare professionals. As if we must do what they say without any questions or thought on our parts.
This is even more coomon amongst women. Who are taught to be quiet, complient and not make a fuss. You did what needed to be done.
