Does having a favorite child mean you love them more?

I was just wondering because it has been pointed out a lot that out of the five kids my sister is my dad’s favorite. She got straight A’s in high school, speaks and writes his native language, speaks Spanish, and has her master’s degree.

My bf said it was silly for me to not want to hear it because his sister is his parent’s favorites and he doesn’t care.

My mom tells me I’m her favorite child and I hate hearing it because I feel like its wrong and puts pressure on me to be a certain way for her. But I guess I’m closer to her because I clean for her and well I’m the only child stuck living at the house (lol) other than my lazy selfish brother.
