Are they right?

My niece is 5. Everytime I get onto her for doing something wrong she gets upset. Like she feels terrible that she did it and is always apologetic to me. Im a teacher (church preschool). When I do it I use my teacher voice. I'm stern but not mean. She like boohoo cries. My sister (her mother) & father say she acts like that because she looks up to me and doesn't like to disappointment me. I just don't know what to think. I said today maybe I should stop getting onto her 😅🤷‍♀️. What do y'all think? And be nice.
