Devouring everything from teen trash to classics. Pretty much had free reign over what I wanted to get from the library/ buy at book shops. If I got into an author or a series I tried to read everything by them. My mother would also buy me classics that I wouldn't have chosen but I read them anyway, which was great not only in exposure, but in terms of more challenging content at a younger age. Not that YA fiction won't do that, but less so. Basically, encourage, make suggestions, but don't force it. Any that I missed out on, and there are still lots, I picked up later. Because I already had a strong foundation, it was easy to do so.
