Raising a reader

My daughter is 6 years old and reads chapter books. We borrow a lot from the library and she reads 30 mins daily independently and (knock on wood) enjoys it. She has a tendency to read just 1 chapter a day from each book and move to the next one, instead of finishing an entire book. Should I be correcting this behavior or just allow her to develop her own reading practices? I’m trying hard to push back my “finish what you’ve started” instinct.
