Ginger Haired babies

Hi I have a 5 week old gorgeous little fire engine red haired baby girl whose eyebrows too are ginger and eyelashes are light blonde and skin a fair tone that goes pinkish. Her eys are very blue too. My husband has the red gene in his family but is blonde and I didnt think there was a red gene in my family. What are the chances of her hair colour changing? I hear ginger is quite dominant so once it shows on their head it tends to stay? I have no problem with her hair colour but just wanted to hear of other peoples experiences. She currently has quite a lot of hair.
